Northern Indiana is a region of the U.S. State of Indiana, including 26 counties which border the states of Illinois, Michigan, and Ohio. Northern Indiana is also considered part of the Great Lakes Megalopolis. The area is generally classified into other sub-regions; Northwest Indiana (or the Calumet Region) is closely tied with Chicago economically and culturally and is considered part of the Chicago metropolitan area. The north central (or Michiana) centers around South Bend metropolitan area, with economic connections to southwest Michigan. Northeast Indiana is centered around the Fort Wayne metropolitan area.
The Northern Indiana landscape is physically characterized by flat, rolling terrain, ranging from 600 to 1,000 feet (180 to 300 m) above sea level. Glacial kettle lakes are found throughout Northeast Indiana, with sand dunes sharing the Lake Michigan shoreline with heavy industry in the northwest. Kosciusko County is home to the largest natural lake (Wawasee) and deepest natural lake (Tippecanoe) in the state of Indiana. The Eastern Continental Divide runs through the region following the top of the Valparaiso Moraine. Besides a few urban areas, much of Northern Indiana lies in the agricultural Corn Belt.

The Inland North dialect of American English is mostly found in the Calumet region of Northern Indiana, due to this area's close cultural ties to Chicagoland where it is prevalent. The Northern cities vowel shift is recognizable in Northwest Indiana and the Michiana area. However, the rest of Northern Indiana tends to exhibit North Midland dialect, with little recognizable influences. Because of the city's transitional location between the Inland North, North Midland, and Central Midland dialects, Fort Wayne has been difficult for linguists to define, with some labeling speech here "virtually accent neutral," attributed to historical settlement patterns.
Northern Indiana bases much of its economy around manufacturing, distribution and transportation, and medical devices. Outside the metropolitan areas, the region's agricultural sector is abundant, given its location within the Corn Belt. Despite the region's storied history in industry, Northern Indiana is also at the heart of the Rust Belt, an area of the U.S. that has suffered deindustrialization and some economic stagnation since the late-20th century.
The Calumet region of Northwest Indiana is home to much heavy industry, notably steel mills. The Calumet region is the nation's second-largest steel producing area. U.S. Steel's Gary Works (in Gary) was once the largest steel mill in the world and employed 30,000. Gary Works remains the largest integrated steel mill in North America. Operated by BP, the Whiting Refinery (in Whiting) is the fifth-largest oil refinery in the nation, processing 405,000 barrels (64,400 m3) of crude oil daily. Northwest Indiana is also a vital trade and shipping center for the state. The Port of Indiana–Burns Harbor handles more ocean-going cargo than any other Great Lakes port in the U.S. Gambling is another important component to the Calumet region's economy, with five riverboat casinos on Lake Michigan (Ameristar, Blue Chip, Horseshoe, Majestic Star, and Majestic Star II).
The north central area of Northern Indiana, centered around Warsaw, is home to several companies specializing in the development and production of orthopaedic medical devices. Nearly one-third of the $38 billion global orthopaedic industry is concentrated in north central Indiana. Elkhart and surrounding municipalities in the Michiana region are home to the largest concentration of recreational vehicle and mobile home manufacturers in the U.S., including Forest River, Gulfstream Coach, Heartland Recreational Vehicles, Jayco, and Monaco Coach, among several others. Some 83 percent of American RVs are produced in Elkhart County.
Benton County is home to several wind farms, including the Benton County Wind Farm, Hoosier Wind Farm, Meadow Lake Wind Farm, and Fowler Ridge Wind Farm, the largest of its kind in the American Midwest and twelfth largest in the world.
