Allen County is a county in the U.S. state of Indiana. As of the 2020 Census, the population was 385,410,[1] making it the third-most populous county in Indiana. The county seat and largest city is Fort Wayne, the second largest city in Indiana.[2]

Allen County is included in the Fort Wayne Metropolitan Statistical Area and the Fort WayneHuntingtonAuburn Combined Statistical Area. Allen County is the cultural and economic center of northeastern Indiana. The county is within a 200-mile (320 km) radius of major population centers, including Chicago, Cincinnati, Cleveland, Columbus, Detroit, Indianapolis, Louisville, Milwaukee, and within a one-day drive of one-third of the U.S. population and one-fifth of Canadians.[3]

Occupied for thousands of years by cultures of indigenous peoples, Allen County was organized by European Americans on December 17, 1823, from Delaware and Randolph counties; and formed on April 1, 1824, at the Ewing Tavern. The county is named for Colonel John Allen, an attorney and Kentucky state senator who was killed in the War of 1812.[4] Fort Wayne, founded at the confluences of the Maumee, St. Joseph, and St. Marys rivers, was chosen as the county seat in May 1824.
