Pontotoc County Courthouse, County courthouse in Ada, Oklahoma, United States

Pontotoc County Courthouse is a county courthouse in Ada, Oklahoma, built in 1926 and listed on the National Register of Historic Places in 1984. The building occupies a central location in downtown Ada and serves as the county's main judicial facility. It underwent extensive remodeling in 2011.

The building was constructed in 1926 and gained National Register listing in 1984 for its architectural importance. It reflects Ada's development as a county administrative center during the early 20th century.

The courthouse has anchored downtown Ada since 1926, when Pontotoc County built it as its seat of government. Court sessions and county business still bring residents into the building, and its 1984 listing on the National Register made it a reference point for local preservation efforts.

The building sits easily walkable from downtown Ada on a spacious lot that sets it apart from street noise. Visitors can view the exterior at any time, while interior access depends on standard business hours.

The structure underwent substantial renovations in 2011 that introduced modern utilities and systems while preserving its original facade and interior details. This work demonstrates how historic buildings can adapt for contemporary use.
