The USS Barker was a Federation starship in service to Starfleet in the early 24th century. Its commanding officer in the 2330s was a man named Connors.

In late 2335 or early 2336, three Barker officers -- first officer Commander Samir al-Halak and Lieutenants Strong and Thex -- undertook a mission to Ryn III for Starfleet Intelligence, during which the Barker were to wait outside Ryn space to rendezvous with their shuttle. When both Strong and Thex died during the course of the mission, Connor and Halak agreed that it would be better if Halak transferred off the Barker to a new ship. (TLE novel: Well of Souls)
