The USS Tucumcari (PGH-2) was a Boeing-built hydrofoil. Named after Tucumcari, New Mexico, it was the basis for the technology used in the subsequent Pegasus-class patrol boats and the Jetfoil ferries. Its unique feature was a waterjet propulsion and a computer-controlled fully submerged foil configuration of one foil at the bow and foils on the port and starboard sides. The Tucumcari was one of two prototype boats contracted by the Navy under project SCB 252 for the purpose of evaluating the latest hydrofoil technology. The second boat was the rival Grumman-built USS Flagstaff (PGH-1).

Tucumcari is a city in and the county seat of Quay County, New Mexico, United States. The population was 5,278 at the 2020 census. Tucumcari was founded in 1901, two years before Quay County was established.
