SS Jeremiah O'Brien is a Liberty ship built during World War II and named after the American Revolutionary War ship captain Jeremiah O'Brien (1744–1818).

Now based in San Francisco, she is a rare survivor^[a] of the 6,939-ship 6 June 1944 D-Day armada off the coast of Normandy, France.^[5]

Of the 2,710 Liberty ships that were built, only the Jeremiah O'Brien and the SS John W. Brown (both operational as of 2024) and the SS Hellas Liberty (a static museum ship) are still afloat.^[6]
