The Brooklyn Historic Railway Association (BHRA) was a non-profit organization dedicated to returning trolleys to the streets of Brooklyn, NY.

The BHRA's origin began with the rediscovery of the Atlantic Avenue Tunnel by Bob Diamond in 1980. BHRA was formed in 1982 to restore the historic tunnel. The Atlantic Avenue Tunnel (constructed in 1844) is the world's oldest subway tunnel. BHRA successfully filed and received designation for the tunnel on the National Register of Historic Places.

As of June 30, 2003, BHRA was ordered to remove and fill in all trolley tracks on public streets by the DOT. The DOT revoked consent for the project to proceed or exist on city streets. Shortly thereafter, BHRA completely ceased operation. Most of the PCC trolleys were removed from Brooklyn. Only the trolleys that are on the Beard Street Pier itself remain. The disposition of the last few trolleys is pending. The BHRA organized tours of the Atlantic Avenue Tunnel have also ended. A new, separate organization, Brooklyn City Streetcar Company, has been formed to attempt to return trolleys to other parts of Brooklyn.
