1869 Philoctetes /fɪləkˈtiːtiːz/ is a Jupiter trojan from the Greek camp, approximately 23 kilometers in diameter.

It was discovered on September 24, 1960, by the Dutch and Dutch–American astronomers Cornelis van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory on Palomar Mountain, California.[4] The asteroid was named after Philoctetes from Greek mythology.[3] On the same night, the same group also discovered 1868 Thersites.
