Oklahoma County Courthouse, Art Deco county courthouse in Oklahoma City, United States.

The Oklahoma County Courthouse is an 11-floor concrete building at 321 Park Avenue in Oklahoma City, designed by Layton & Forsyth in an art deco / art moderne style loosely abstracted from stepped-back Mayan temples. Its sandy-brown Indiana limestone carries inscribed quotes and a carved mural of a Native American figure and a Mountain Man. Inside, a two-story lobby has a terrazzo floor with a compass design, wagon-wheel chandeliers and third-story overlooks.

The courthouse was built in 1937 to replace an earlier courthouse from the 1900s at California and Robinson, funded by $100,000 in bonds. Its $1.5 million cost came from a bond issue and the Public Works Administration, a federal program creating jobs during the Great Depression. It was listed on the National Register of Historic Places on March 5, 1992.

Quotations are carved into the sandy-brown Indiana limestone of the facade, and a carved mural shows a scene of Oklahoma friendship between a Native American figure and a Mountain Man. Inside, the two-story lobby has a terrazzo floor laid with a compass design and wagon-wheel chandeliers, with overlooks at the third story.

The courthouse is located downtown and operates during standard business hours on weekdays. The main entrance is easily accessible from the street, and the plaza in front provides space to view the exterior architecture.

The two-story lobby has a terrazzo floor inlaid with a compass design and hangs abstracted wagon-wheel chandeliers, with a third-story overlook above.
