Lake Grouse (or Grouse Lake) is a small lake of glacial origin located on the Kenai Peninsula in the U.S. state of Alaska, approximately north of Seward. The name first appeared in a 1906 United States Geological Survey record reported (from a local name) by cartographer Moffit.
Salvelinus malma (Dolly Varden) trout can be fished in this lake. Ice fishing is possible from December to April.
