Allen County is a county in the U.S. state of Indiana. As of the 2010 Census, the population was 355,329,  making it the third-most populous county in Indiana. The county seat and largest city is Fort Wayne. 
Allen County is included in the Fort Wayne Metropolitan Statistical Area and the Fort Wayne– Huntington– Auburn 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 Ontario, Canada, and within a one-day drive of one-third of the U.S. population and one-fifth of Canadians. 
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.  Fort Wayne, founded at the confluences of the Maumee, St. Joseph, and St. Marys rivers, was chosen as the county seat in May 1824.

The Allen County Courthouse was designed by Brentwood S. Tolan of Fort Wayne, and was built by James Stewart and Company of Saint Louis, Missouri. When the cornerstone was laid in 1897, the oldest man in the county, Louis Peltier, was present; he remembered Fort Wayne when it was a fort. The courthouse was completed in 1903 at a total cost of $817,553. Built in the Beaux-Arts architecture style, it was one of the most expensive courthouses in the state. It also was filled with artwork that cost more than other entire courthouses of the time. The courthouse has been protected as a National Historic Landmark since 2003. The building is now used primarily as a government annex, as most of the offices were moved across Main Street to the Edwin J. Rousseau Centre in 1971.
