Peoria Federal Building and U.S. Courthouse, Courthouse and former post office in Peoria, Illinois, United States

The Peoria Federal Building and U.S. Courthouse is a courthouse and former post office in Peoria, Illinois, built in 1938. The building displays clean, geometric Moderne style with massive granite facades, decorative limestone work, and carved stone panels above the main entrance.

The U.S. Post Office and Courthouse was built in 1937–38 with plans by Supervising Architect Louis A. Simon and Howard Lovewell Cheney as architect of record. It housed Peoria's main post office until 1981 and was listed on the National Register of Historic Places on October 24, 2012.

The building's name reflects its dual role as a courthouse and post office that shaped daily life in Peoria for decades. Stone carvings on the facade depict working people, agricultural scenes, and a postal worker, reflecting the roles that support the community.

The building is an active federal courthouse at 100 Northeast Monroe Street, so interior access is subject to court security; the granite exterior and limestone carvings can be seen from the street. The bas-relief panels by Freeman L. Schoolcraft sit above the Main Street entrance, facing the side where visitors pass.

The four bas-relief panels above the Main Street entrance, carved by Freeman L. Schoolcraft, show a man of industry, a woman of agriculture, a Native American and a postal worker. Look for the postal worker among them, a nod to the main post office the building housed until 1981.
