Ehyophsta (Cheyenne for "Yellow-Haired Woman") was a Cheyenne woman. She was the daughter of Chief Stands-in-the-Timber and the niece of The Old Bad Faced Bull.

She was a great woman warrior. She fought in the Battle of Beechers Island in 1868, and also fought the Shoshone that same year, where she counted coup against one enemy and killed another. She fought the Shoshone again in 1869.

Ehyophsta was also a member of a secret society composed exclusively of Cheyenne women.

She was one of the last fighting Cheyenne women. She died in 1915.
