Kerenzerberg Pass (el. ) is a mountain pass in the Alps in the canton of Glarus, Switzerland. It connects Mollis and Mühlehorn above Lake Walen ().
The pass road was built in 1848 and has a maximum grade of 10 percent. Two tunnels have been dug under the pass, a road tunnel for the A3 motorway () and a rail tunnel for the Ziegelbrücke to Sargans railway line. The latter replaced a series of previously built railway tunnels along the lake; this old route has been converted to a bike route (National Route 9).
The area is known for both summer and winter sport.
