Little Mink Lake is a lake in the Moira River and Lake Ontario drainage basins in Addington Highlands, Lennox and Addington County in Ontario, Canada. A Hydro One transmission line crosses over the west end of the lake. The lake is about 0.7 km long and 0.35 km wide and lies at an elevation of 340 m about 12 km northeast of the community of Gunter and 18 km northwest of the community of Cloyne. There are two unnamed creek inflows at the east, and one unnamed creek primary outflow, at the west, towards Little Merrill Lake. Its waters flow via Merrill Creek, Partridge Creek, the Skootamatta River and the Moira River into the Bay of Quinte on Lake Ontario at Belleville.
