USNS Bruce C. Heezen (T-AGS 64) is a Pathfinder-class oceanographic survey ship. It is the fifth ship in the class.
She is named after Bruce C. Heezen, who was the leader of the team from Columbia University that discovered the Mid-Atlantic Ridge during the 1950s. The ship was the first Navy vessel to be named by civilians. Nine students from Oaklawn Elementary School in Cranston, RI named the ship after winning a contest sponsored by the Navy. Amanda Baillargeon, James Coogan, Meagan Durigan, Stephen Fish, Patricia Gumbley, John Lucier, Sara Piccirilli, Dana Scott, and Rebecca Webber were led by their teacher Marilyn Remick.
