Lake Nepahwin is a lake in Sudbury, Ontario, located to the south of the city's downtown area.
Origin of the name
Its name was derived by settlers from the Anishinaabemowin name nibaawin: the root verb nibaa (to sleep) plus the suffix win which turns it into a noun, hence "sleeping lake". The name was adopted on August 4, 1949 following a community plebiscite.
