Prosopium is a genus of fish in the trout/salmon family Salmonidae. The six species are primarily known from North America. However, the round whitefish P. cylindraceum is also widely found in the rivers of Siberia and the Pygmy Whitefish Prosopium coulterii is found in a certain lake in Chukotka Autonomous Okrug, the Ekityki Lake.

Three of the species (Prosopium gemmifer, Prosopium spilonotus, and Prosopium abyssicola) are endemic to Bear Lake on the Utah-Idaho border.
