René C. Davidson Courthouse, Courthouse in downtown Oakland, California, US

The René C. Davidson Courthouse is an Art Deco courthouse completed in 1934 on the edge of Lake Merritt in Oakland, California. Its facade bears the inscription "Alameda County Court House." It was the main courthouse of the Alameda County Superior Court system and also housed the Clerk-County Recorder's office until 2000.

The building opened in 1934 to replace a courthouse from 1893 that no longer met the needs of a growing county. It was built during a period when many public institutions across the US were being rebuilt in the then fashionable Art Deco style.

The Art Deco facade uses geometric shapes and pale stone that stand out along the streets of downtown Oakland. This visual style was common in public buildings of the 1930s and was meant to communicate order and civic seriousness.

The courthouse sits in downtown Oakland and is easy to reach by train, with a station within walking distance. As an active court building, security checks at the entrance are standard and public access is limited to certain areas.

The building's inscription still reads "Alameda County Court House"; it was renamed for René C. Davidson, the longtime County Recorder, after his death. Another name proposed was that of Jack G. Blue, Davidson's immediate predecessor. In 2016 it emerged that the FBI had hidden microphones outside the courthouse between March 2010 and January 2011 without a warrant, during a bid-rigging investigation.
