Annie Webb Blanton (19 August 1870 in Houston – 2 October 1945 in Austin) was an American suffragist from Texas, educator, and author of a series of grammar textbooks.

Blanton attended the University of Texas in Austin, earning a degree in English literature in 1899.

She was elected president of the Texas State Teachers Association in 1916, the first woman to hold that position.

Blanton was professor of English at the North Texas State Normal College in Denton from 1901 to 1918.

When Blanton moved to Austin, Mitchell left her job to follow; the pair traveled together, and hosted social gatherings in their home.
