A Gavarian ship was a type of starship utilized during the mid-22nd century.

Sometime prior to late-2151, a Ferengi starship, commanded by the Ferengi merchant Ulis, raided a Gavarian starship. Ulis and his crew discovered the ship's' vault designed similar to the enclosed biobed scanner located in the sickbay of Enterprise NX-01. (ENT: "Acquisition")

According to Star Trek: Star Charts ("United Federation of Planets I") and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), there was a star system named Gavaria (Sigma Pegasi), which might possibly be the system of origin for this ship, in the Alpha Quadrant. This was a trinary system with a pair of F-class stars and a M-class star. In the late 24th century, it was an independent system.
