Sarah Warren Keeler (3 May 1844 – 13 September 1899) was an American educator and teacher who founded and was principal of a school for the deaf-mute in New York.

After leaving the institution, she was the principal of her own Keeler Private Articulation Class for Deaf-Mutes from 1885 to 1893, a private class for an average of nine students a year aged nine to eighteen[2] taught by herself and her small staff, run in connection with her school for young women at various locations in New York before settling at 27 East Forty-Sixth Street.

[citation needed] In her obituary, her brother George Keeler wrote that at her school, Keeler met "with unvarying success" in bringing the deaf "to a knowledge of the world outside of the silent one they occupied".

[1][3] The obituary by her brother described Keeler as loving, kind and faithful as she went forward with her work.

She fell from her wheel and sprained her foot and knee, came back to New York for treatment, and had a paralytic stroke that rendered her speechless and paralysed her right side.
