Lieutenant Ben Prieto was a Starfleet officer in the late 24th century.

In 2364, he was assigned to the USS Enterprise-D and piloted a shuttle carrying Counselor Deanna Troi. On the way back to the Enterprise-D, it crash landed on the planet Vagra II. Lieutenant Prieto suffered heavy injuries, but was able to recover once he returned to the Enterprise-D. (TNG: "Skin of Evil")
