Lake Mâţelor (Romanian; Moldavian; Moldovan: Lacul Mâţelor) is a natural salt lake in the town of Ocna Sibiului, Sibiu County, Transylvania, Romania. It is one of the many lakes of the Ocna Sibiului mine, a large salt mine which has one of the largest salt reserves in Romania.

The salt mine on which it is located is not documented, but it was exploited in the late middle-ages with a bell-system, at a depth of more than 80 m through two wells.
