USS PT-129 was a motor torpedo boat of the United States Navy, a PT whose work was the fast night patrol.
On the night of 24–25 October 1944 she was on patrol in Surigao Strait. Thirty-nine motor torpedo boats were out that night, and PT-129 was one of them.
The Battle of Surigao Strait, dated 25 October 1944, lists her in that motor torpedo boat patrol. Her recorded part in the battle is the patrol in the strait.
The note on her fate returns to those same hours. It names her as one of the motor torpedo boats on patrol in Surigao Strait on the night of 24–25 October 1944.
