USS General J. C. Breckinridge (AP-176) was a troopship that served with the United States Navy in World War II, the Korean War and the Vietnam War. In October 1949 she was redesignated T-AP-176 but retained her Navy crew. Her namesake was United States Marine Corps Lieutenant General James Carson Breckinridge (1877-1942), who was the grandson of John Cabell Breckinridge, who served as Vice President of the United States from 1857 to 1861.

The P2 transport was a United States Maritime Commission design for a passenger ship which could be readily converted into a troop transport. Three variants of the design were built, the P2-SE2-R1 (Admirals), P2-S2-R2 (Generals), and P2-SE2-R3 (Presidents).
