Gennady Viktorovich Samokhin (born July 14, 1971 in Simferopol) is a Crimean speleologist. He was educated and works in the Tavrida National V.I. Vernadsky University.

Gennady Samokhin holds the cave diving depth world record when setting successive world records of 2,191 m in 2007 and 2,197 m in 2012. Both records were achieved at Krubera Cave in Georgia which remains the only known cave on Earth deeper than 2,000 metres.

Cave diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers lost while diving for one of these reasons. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave diving is done using scuba equipment, often in specialised configurations. Recreational cave diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves decompression.
