36P/Whipple is a periodic comet in the Solar System. It is the lowest numbered Quasi-Hilda comet.[4] It passed 0.25 AU (37 million km) from Jupiter in June 1922.[2]

The comet nucleus is estimated to be 4.5 kilometers in diameter[2] or 5.1 kilometers. The rotational period was estimated to be about 40 hours.[5]
