Rancho Cucamonga is a city of about 177,000 residents located just south of the foothills of the San Gabriel Mountains and Angeles National Forest in San Bernardino County, California, United States. About 37 miles (60 km) east of Downtown Los Angeles, Rancho Cucamonga is the 19th most populous city in southern California and the 27th state-wide. The city's seal, which centers on a cluster of grapes, alludes to the city's agricultural history including wine-making. The city's proximity to major transportation hubs, airports, and highways has attracted the business of several large corporations, including Coca-Cola, Frito-Lay, Big Lots, Mercury Insurance Group, Southern California Edison, and Amphastar Pharmaceuticals.
The city had a population of 165,269 according to the 2010 United States Census and the Census Bureau estimated the population to be 177,452 in 2017. The city experiences an average of 287 sunny days per year, compared to a national average of 205 days. Its climate is classified as warm Mediterranean, or Csa, under the Köppen climate classification system.
The city's favorable location and host of public amenities have earned it numerous distinctions. Notably, Money Magazine ranked Rancho Cucamonga 42nd on its "Best Places to Live" list in 2006. In addition, Insider Magazine established one Rancho Cucamonga neighborhood as the 13th richest neighborhood in Southern California. The four public high schools (Alta Loma, Etiwanda, Los Osos, and Rancho Cucamonga) earned the Silver distinction in a 2015 ranking of the nation's high schools by U.S. News & World Report. In 2017 the California Department of Education announced that all four high schools were being named California Gold Ribbon Schools.

Rancho Cucamonga's first settlers were Native American. By 1200 AD, Kukamongan Native Americans had established a village settlement in the area around present-day Red Hill, near the city's western border. Kukamonga derives its name from a Native American word meaning "sandy place." Anthropologists have determined that this cluster of settlers likely belonged to the Tongva people or Kich people, at one time one of the largest concentrations of Native American peoples on the North American continent. In the 18th century, following an expedition led by Gaspar de Portola, the land was incorporated into the Mission System established by Father Junipero Serra and his group of soldiers and Franciscan friars.
After a half century of political jockeying in the region, the land finally came under the control of Juan Bautista Alvarado, governor of Mexico. On March 3, 1839, Alvarado granted 13,000 acres of land in the area called "Cucamonga" to Tubercio Tapia, a first-generation Spanish native of Los Angeles, successful merchant, and notorious smuggler. Tapia went on to establish the first winery in California on his newly deeded land. Rancho Cucamonga was purchased by John Rains and his wife in 1858. The Rains family's home, Casa de Rancho Cucamonga, was completed in 1860 and now appears on the National Register of Historic Places.
During the ensuing years the town prospered and grew. In 1887, irrigation tunnels were dug into Cucamonga Canyon by Chinese laborers and the Santa Fe Railroad was extended through the area. Among the town's economic mainstays was agriculture, including olives, peaches, citrus, and, most notably, vineyards. In 1913, the Pacific Electric Railway was extended through Rancho Cucamonga in an effort to improve crop transportation. Several landmarks in existence today pay tribute to the city's multicultural founding. In particular, Our Lady of Mt. Carmel remains as a relic of the area's Mexican agriculture laborers while the Chinatown House stands as a reminder of the Chinese immigrants who labored in constructing the area's infrastructure.
The former community of Grapeland, first settled in 1869, lay roughly between today's Victoria Groves Park and Central Park. There was a schoolhouse which also doubled as a church. In 1890 an irrigation district was formed and $200,000 in bonds were sold to pay for improvements. The Sierra Vista reservoir was built in 1886-87 by J.L. Scofield as the focal point of a network of irrigation pipes. The system was unused, however, because the bond issue was declared illegal. "Orchards and vineyards began to die," The Daily Report newspaper reported in a retrospective. "Residents moved out. The post office closed in 1905. Homes, buildings were destroyed or abandoned." The reservoir remained unused until 1956, when the Fontana Union Water Company filled it with 5 million gallons of water. The local school district was merged with the Etiwanda district in 1901. In 1957 the settlement was practically deserted, but there were still rabbit-proof stone walls marking boundaries of previous citrus orchards.
Rancho Cucamonga is part of the Inland Empire and San Bernardino County, a region that lies inland from the Pacific coast and directly east of Los Angeles County. Rancho Cucamonga is located about 37 miles (60 km) east of Los Angeles, bordered by Upland to its west, Ontario to its south, the San Gabriel Mountains to its north and I-15 and Fontana to its east. The city sits atop an alluvial plain and views of Cucamonga Peak, one of the tallest peaks of the San Gabriel Mountains, are available from all points throughout the city. The city has a total area of 39.9 square miles (103 km2), 99.95% of which is land and 0.05% water.
The city's climate is classified as hot-summer Mediterranean, or Csa, under the Köppen climate classification system. Yearly precipitation is 17.68 inches (449 mm) and the city experiences an average of 287 sunny days per year, compared to a national average of 205 days.

While most of the city's land area is devoted to residential areas, Rancho Cucamonga, like its neighbors Ontario and Fontana, is a major center for the logistics industry in Southern California. This is due to its proximity to two interstate highways and Ontario International Airport, and the space afforded by the large tracts of former agricultural land in the southern section of the city.
In the area around Milliken Avenue, between Archibald and Etiwanda Avenues, Foothill Boulevard, and Fourth Street, about seven square miles of land are primarily occupied by numerous massive distribution centers, and even more, smaller manufacturing companies. This area is ringed by office parks, mostly along Haven Avenue, and shopping strips, such as the Terra Vista Town Center (part of a nearly two-square-mile master-planned community in the center of the city), and malls, such as Victoria Gardens, and the Ontario Mills, across Fourth Street in Ontario.
The city is also home to a CMC Steel (Formerly Gerdau, Formerly TAMCO Steel) minimill, the only producer of long steel in California. This mill recycles ferrous scrap, such as junked cars and appliances, to produce rebar.
Victoria Gardens is a lifestyle center near the eastern end of the city, at the intersection of Foothill and Day Creek Boulevards. Since the city had never developed a traditional commercial downtown like neighboring cities Ontario and Upland had, efforts were made in the design of Victoria Gardens to bring elements of more traditional and urban town design to what had historically been a suburban city. While retaining many characteristics of traditional shopping malls, such as large anchor stores, a food court, and vast parking lots and garages, the smaller stores are arranged as city blocks in a grid of two-lane streets, featuring lush landscaping and metered "teaser parking" in front of the stores, which open onto the sidewalk. There are two "Main Streets", which run from west to east across the center. Running from north to south between them is a pedestrian axis leading from one of the Macy's anchor stores, through a "town square" between a pair of mixed-use office buildings, to the Victoria Gardens Cultural Center, which contains the Lewis Playhouse (a 570-seat theater) and a branch of the city library. The east side of the development has Southern California's only Bass Pro Shops Outdoor World superstore; the 180,000-square-foot (17,000 m2) facility includes a Tracker Boat Center and the Islamorada Fish Company restaurant. There are restaurants throughout the center, both well-known chains and unique eateries, including California Pizza Kitchen, The Cheesecake Factory, N7 Creamery, Fleming's, Gyu-Kaku Japanese BBQ Dining, Johnny Rockets, King's Fish House, Lucille's BBQ, P.F. Chang's China Bistro, Richie's Diner, T.G.I. Friday's, and Yard House. The center features a 12 screen AMC Theatre.

Rancho Cucamonga's location at the base of the San Gabriel Mountains has necessitated the use of numerous control channels and basins to reduce the seasonal flood danger from the several streams descending from the range. In past years, some of the city's roads were known for flooding. Hermosa Avenue, in particular, now features many high curbs and extra-large storm drain grates to reduce flooding.
Rancho Cucamonga is served by Omnitrans bus service, train service from Metrolink's Rancho Cucamonga station on the San Bernardino Line, and nearby Ontario International Airport, one of four major Los Angeles-area passenger airports with multiple daily flights by most domestic carriers as well as a major shipping hub for companies like UPS and FedEx.
I-15 sits atop an elevated berm, and cuts a curve through the southeastern part of the city, isolating a mostly industrial area, a small shopping center, and several housing tracts from the larger part of the city. Further north, I-15 forms part of the northeastern border with neighboring Fontana before entering the Cajon Pass through the San Gabriel Mountains. I-15 provides connectivity with the High Desert, Nevada, and points north for the Inland Empire and much of Southern California.
SR-210 runs nearly straight east–west through the northern part of the city, roughly bisecting the residential communities of Alta Loma and Etiwanda, providing connection (in addition to I-10 and SR-60) from the San Gabriel Valley and points west to the San Bernardino area.
Rancho Cucamonga receives natural gas from the Southern California Gas Company. The city's water supply and sewage are managed by the Cucamonga Valley Water District. Garbage collection is by Burrtec Disposal, phone service is from Frontier Communications and cable TV is provided by Charter Communications.
Electric power in Rancho Cucamonga is provided by Southern California Edison and the Rancho Cucamonga Municipal Utility, and the city is also home to the Reliant Energy Etiwanda Generating Station, on Etiwanda Avenue. This facility, one of five Reliant stations in California, is a natural gas-fired power plant, which began operation in 1963. At 640 megawatts (860,000 hp) net capacity, it is Reliant's second-highest capacity plant on the West Coast. It utilizes four steam turbine generators; of which units three and four are currently active. Steam turbines one and two, as well as a combustion turbine, were retired in 2003 and 2004, respectively. Several systems are in place to control gas emissions, and annually, over 900,000,000 US gallons (750,000,000 imp gal; 3.4 GL) of recycled water are used for cooling.
On November 29, 2011, The Inland Empire Utilities Agency has installed the first wind turbine in Rancho Cucamonga.
In popular culture
The name "Cucamonga" became well known to fans of Jack Benny's popular radio program, in which an announcer, voiced by Mel Blanc, would call out: "Train leaving on track five for Anaheim, Azusa and Cu-camonga!" This running gag became so well known that it eventually led to a statue of Benny in Cucamonga.
Bugs Bunny cartoons feature numerous references to Cucamonga. In Mutiny On the Bunny, Cucamonga is one of the stickers on the boat at the end of the cartoon that Bugs is riding in. In My Bunny Lies Over The Sea, Bugs reads map directions that include "turn left at Cucamonga".
On the Grateful Dead's 1974 album From the Mars Hotel the title of the song "Pride of Cucamonga", written by Robert Petersen and sung by Phil Lesh, refers to "the label of a jug wine produced in the late 1960s by the Joseph Filippi Winery in Rancho Cucamonga."
Rancho Cucamonga has been featured on the Comedy Central hit show Workaholics where it was nicknamed "Hollywood East". The main characters are said to live in the heart of Rancho Cucamonga.

- "Rubble Remains of a Community That Was — Grapeland," The Daily Report, July 13, 1957, page 3 / FONTANA–Between Fontana and Etiwanda lie the dry, dusty remains of a community that died for lack of water. The name of the town was Grapeland. A few people still live in the original tpwnsite, but the brilliant future that was predicted for it in the 1880's never came to pass. Unpaved dirt roads, still graded by San Bernardino County, run spasmodically through the area. Grapevines still cover much of the parched land; but gone are the citrus groves, the fruit trees, the early pioneer settlers. . . . The first settlers came to Grapeland in 1869. Later, more and more arrived, until in 1890 the need for adequate water became imperative. An irrigation district was formed and $200,000 in bonds were sold. With this money, the Sierra Vista Reservoir was built as the focal point of a network of irrigation pipes. It was to remain unused for 66 years, for the entire bond issue was declared illegal. Orchards and vineyards began to die. Residents moved out. The post office was closed in 1905. Homes, buildings were destroyed or abandoned. Today, the hot sun parches the empty fields of Grapeland—the community that died of thirst. / Still in fairly good shape along Grapeland's ghost roads are rabbit-proof stone walls around long-gone ciitrus orchards. / CONSTRUCTED 1886-1887, J.L. Scofield, Engineer and Builder is the legend proclaimed by this plaque in the Sierra Vista Reservoir, which proved a delusion to settlers. It remained dry until 1956, when the Fontana Union Water Co. plastered its colorful pebbly exterior and filled it with 5,000,000 gallons of water.
