The USS Clement (NCC-12537) was a Federation starship that was in service to Starfleet in the latter half of the 24th century.
In 2370 the USS Enterprise-D was supposed to meet with the Clement, but the rendezvous was delayed when the Enterprise was ordered to the Argaya system. (TNG: "Lower Decks")
In 2374, the Clement suffered heavy casualties during the war, a week before the Dominion invaded Betazed. Casualties from the Clement, including Commander Grace Kenney, were listed on a casualty report on Deep Space 9. (DS9: "In the Pale Moonlight")
