Marguerite Stitt Church (September 13, 1892 – May 26, 1990) was an American psychologist and politician who represented Illinois' 13th congressional district as a Republican from 1951 to 1963.

She traveled abroad with her parents each summer, which helped develop her interest in foreign countries.

When her husband, Ralph Church, was first elected as a U.S. Representative in 1934, she became closely involved with his work.

[2] Church ran for her husband's now vacant seat and was elected in November 1950 by the highest majority ever had by a candidate from Evanston.
