USS Pennsylvania (BB-38) was a Pennsylvania-class battleship of the United States Navy. Newport News built her. She was launched on 16 March 1915 and commissioned on 12 June 1916.
On 7 December 1941, during the attack on Pearl Harbor, she lay in Dry Dock No. 1 with Cassin and Downes. One bomb hit her there and damaged the ship. She stayed afloat.
In the Marshall Islands she bombarded Kwajalein from 31 January 1944. She then bombarded Engebi and Parry at Eniwetok. On 25 October 1944 Pennsylvania stood in the battle line at the Battle of Surigao Strait.
Jesse Barrett Oldendorf flew his flag in Pennsylvania on 12 September 1944, and his flag was in her again on 12 August 1945. On both dates he was the flag officer embarked in the battleship, a post apart from command of the ship itself. Pennsylvania survived the war. The hull was later expended as a target.
