McKinleyville (formerly, Minorsville) is a census-designated place (CDP) in Humboldt County, California, United States. McKinleyville is located 5.25 miles (8.4 km) north of Arcata, at an elevation of 141 feet (43 m). The population was 15,177 at the 2010 census, up from 13,599 at the 2000 census. This unincorporated community is the third largest community, after Eureka and Arcata, on the far North Coast and larger than five of seven cities in the county. It is also the location of the Arcata-Eureka Airport, the largest airport in Humboldt County and the region.
McKinleyville is a community made up of a combination of smaller settlements. Joe Dow settled in the general area in the 1860s and that area was known as Dow's Prairie. Slightly south was a small community called Minor (also known as Minorville). Minor was first settled in the late-19th century. Just south of Minor was Calville. Calville was settled by the employees of the California Barrel Company. After President William McKinley was assassinated in 1901 the community of Minor changed its name in his honor. All three areas are collectively considered to be what is now known as McKinleyville. Dow's Prairie continues to be known by the original place name and, although it is considered part of McKinleyville, local residents further refine location by this neighborhood name. , 
The first post office at McKinleyville opened in 1903, closed in 1921, and was re-opened in 1955.
The area had several nicknames. Derogatory names such as "Oklahoma by the Sea", "MACK Town", "McHickleyville" and "McKinleymobile" came from the area historically having lower property values, and a larger concentration of mobile homes.
McKinleyville is now a bedroom community with mainly retail and professional businesses to serve its residents. Major entertainment, county services, educational facilities and local industry can be found in nearby Arcata and Eureka. Property values increased dramatically in the late 1990s and the early first decade of the 21st century, and the larger McKinleyville community has experienced gentrification. The community has discussed incorporating into a city in the past, but long term plans have not materialized.
According to the United States Census Bureau, the CDP has a total area of 21.0 square miles (54 km2), of which 20.8 square miles (54 km2) is land and 0.2 square miles (0.52 km2), or 1.2%, is water.

U.S. Route 101 extends north and south through the community. The route lies to the west of the majority of the community and bisects a small portion of the area. State Route 299 connects to U.S. Route 101 at the northern end of the nearby city of Arcata. SR 299 begins at that point and extends easterly to serve as the major traffic artery to the east for the community of McKinleyville.
Humboldt Transit Authority (HTA) is the major provider of public bus transportation in McKinleyville and the county. HTA has several stops in McKinleyville. Dial-A-Ride service is available from Humboldt Senior Resource Center through an application process.
At times, vehicle traffic into and out of McKinleyville has been restricted due to landslides on the U.S. routes. A 7.0 magnitude earthquake on November 8, 1980, caused an over-crossing at Tompkins Hill, just south of Eureka, to collapse.
The Hammond Trail consists of over 5 miles (8.0 km) of hiking, biking, and equestrian trails linking Arcata, McKinleyville, and the surrounding areas. Following the historic Hammond Lumber Company railroad grade, the trail begins at the Hammond Bridge – which crosses the Mad River near the Mad River County Park – and extends north to Clam Beach County Park just south of Little River State Beach. There is an overnight campground at Clam Beach County Park.
The Hammond Trail is also a recreation and transportation corridor traveling through rural and suburban areas of Humboldt County and is a part of both the California Coastal Trail (CCT) and the Pacific Coast Bike Route (PCBR).
The Arcata-Eureka Airport is a full service airport located in McKinleyville. The name of the airport comes from the names of the primary population centers that it serves. The location of this airport was chosen to serve as an experimental field to test landing during heavy fog conditions. Due to weather patterns and geographic conditions the area is one of the foggiest in Northern California.
A deepwater port is located roughly 18 miles (29 km) to the south, across the bay from the city of Eureka. The port is serviced in the community of Samoa.
Several small marinas in Eureka are available for private use.
- Clam Beach Run
- Pony Express Days (known temporarily as the Azalea Festival from 2005 to 2008)
- Robert McManus Remembrance Walk/Run
