Pickering Crater is a crater in the Phaethontis quadrangle on Mars, located at 33.1° south latitude and 132.5° west longitude. It is 115 kilometres (71 mi) in diameter.

Two nearby prominent craters are unnamed, the triple crater pair lies to the south-southwest with the larger two being nearly attached and another further southeast. West-northwest is the larger Koval'sky. Located south of Pickering are three recently named tiny craters including Selekac in the south-southaest and Dunkassa to the south-southwest, inside an unnamed mid-sized crater near Dunkassa is also Langtang

Lava flow fronts are visible within the crater, and the source of the lava is Arsia Mons. The lava has flowed around the central peak of the crater.[1] As lava once flowed to the northeast, there are not that many craters towards the northeast of Pickering which are in Daedalia Planum that the eastern rim borders, the only small named crater nearby is Zumba located in the northeast inside the Phoenicis quadrangle.

The crater was named after several people: Edward Charles Pickering, American astronomer (1846–1919); his brother William Henry Pickering, American astronomer (1858–1938); and Sir William Hayward Pickering (unrelated), New Zealand-American engineer (1910–2004).[2]
