Riffe Lake is a 23.5 mi (38 km) long reservoir on the Cowlitz River in the U.S. state of Washington. Originally named Mossyrock Lake, then later Davisson Lake, it was created in 1968 with the construction of Mossyrock Dam by Tacoma Power. The lake was renamed in 1976 after the community of Riffe, which was inundated by the lake. The residents of Kosmos, Washington were also relocated as the lake's water level would submerge much of the town.

The lake contains species of fish including rainbow and brown trout, landlocked coho, bass both large mouth and small mouth, bluegill, crappie, and perch.
