The Third Baptist Church is a rare example of Midcentury Modern ecclesiastical architecture in San Francisco.

Founded in 1852 as the First Colored Baptist Church of San Francisco, Third Baptist Church (renamed in 1855) was the first African American Baptist congregation formed west of the Rocky Mountains and remained the only black Baptist church in San Francisco until the early 1940s.

Reverend Frederick Douglas Haynes Sr., who served as pastor from 1932 to 1971, was an influential leader in the civil rights movement.
