Margaret Greer Amsler (née Harris, formerly Gordon; June 15, 1908 – May 14, 2002) was a law professor in Texas.
Her mother also graduated from Baylor, where she had moved to accompany her older brother who was a professor of Latin and Greek.
She represented McLennan County from 1939 to 1941, one of two women in the Texas House that term, alongside 149 other Democrats.
She was not reelected, but the other woman representative, Neveille Colson served for many years until 1948 and was then a Texas state senator until 1966.
The law school closed from 1944 to 1946 due to the Second World War; when it reopened, she was acting Dean.
She also drafted the Texas Married Women's Act of 1963, to grant rights possessed by men and unmarried women, allowing a married woman to enter into a contract, sue, or sell property without her husband's permission.
