The USS Tecyr (NCC-77545) was a Federation spacecraft, a Starfleet Danube-class runabout in service in the 2380s decade. (DS9 novel: Sacraments of Fire)
The Tecyr and the USS Elestan arrived at Starbase Deep Space 9 at the same time to add to the station's complement of runabouts.
In September of the year 2385, the Elestan performed its duty rotation at Security Outpost Endalla I when the Tecyr arrived for the weekly crew rotation. Lieutenant Commander Wheeler Stinson was in command of the Tecyr and accompanied by three passengers, Ensign Stig Hallström, Crewman Sandra Silverman and Crewman Torvan Pim. Before the rotation commenced, a civilian Bajoran vessel violated Endalla's airspace. Its sole passenger was saved by the Tecyr but the civilian craft itself was lost. (DS9 novel: Sacraments of Fire)
- The Tecyr was, presumably, named after the Tecyr River on Bajor.
