EGMA Sinkhole (), a.k.a. Peynirlikönü Sinkhole, is a sinkhole and the deepest cave in Turkey. It is located at Sugözü village of Anamur, Mersin. The sinkhole is  deep and  long. EGMA is an acronym that stands for Evren Günay - Mehmet Ali Özel.

The cave was discovered and first explored in 1993 by the Boğaziçi University Speleological Society (BÜMAK). A flash flood caused explorer Mehmet Ali Özel to lose his life inside the cave in 2001. In 2004, with the help of members of the Bulgarian Speleological Federation, the BÜMAK team recovered Mehmet Ali's body and also reached the deepest point of the cave.
