Kamensk crater is an impact crater located 10 to 15 kilometres (6.2 to 9.3 mi) to the north of Kamensk-Shakhtinsky town in Rostov Oblast, Russia.

It is 25 km (16 mi) in diameter and the age is estimated to be 49.0 ± 0.2 million years old (Eocene).

[1] It may have formed at the same time as the smaller and nearby Gusev crater.

Six laser total-fusion analyses of the Kamensk impact glass have a weighted-mean age of 49.2 ± 0.1 Ma relative to sanidine from the Taylor Creek Rhyolite of New Mexico, that has an age of 27.92 Ma relative to a K-Ar age of 162.9 ± 0 Ma for a primary fluence-monitor standard SB-3 biotite or of 513.9 Ma for an international hornblende standard MMhb-1.
