The county seat of Madera County is the City of Madera.

The county seat is located at the junction of Highway 99 and Highway 145 on the Fresno River. Officials of the California Lumber Company had the town laid out in 1876 at the end of a flume that brought lumber 63 miles from the mountains to the railroad. Madera means "wood" or "timber" in Spanish.  The Madera Post Office has been open since 1877. The town was incorporated in 1907.
