USS McCandless (FF-1084) was a Knox-class frigate of the US Navy. Commissioned in 1972, she served for 22 years before being decommissioned as a training frigate, and sold to the Turkish Navy as TCG Trakya (F-254). She also participated in Operation Desert Storm in 1991.

The 46 Knox-class frigates were the largest, last, and most numerous of the US Navy's second-generation anti-submarine warfare (ASW) escorts. Originally laid down as ocean escorts, they were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from 'DE' to 'FF'. The Knox class was the Navy's last destroyer-type design with a steam turbine powerplant.
