George Fiske (October 22, 1835 – October 21, 1918) was an American landscape photographer.
Fiske was born in Amherst, New Hampshire and moved west with his brother to San Francisco. He apprenticed with Charles L. Weed and worked with Carleton E. Watkins, both early Yosemite photographers. Fiske and his wife moved to Yosemite in 1879 and lived there until he committed suicide in 1918. Fiske was living alone when he shot himself and he often told his neighbors he was “tired of living.” Most of his negatives were destroyed when his house burned in 1904.
