Matilda Bradford "Tillie" Ehringhaus (née Haughton; October 23, 1890 – June 16, 1980) was an American civic leader who, as the wife of John C. B. Ehringhaus, served as First Lady of North Carolina from 1933 to 1937. Since her time in the North Carolina Executive Mansion was marked by the Great Depression, she made budget cuts and adaptations around the mansion to save money for the state, including having the wattage of the chandeliers lowered so that the electric bill would not exceed monthly expenses. As first lady, she hosted musical salons and was noted for her beauty and charm. After her husband's death, Ehringhaus co-edited the North Carolina Almanac and State Industrial Guide and, in 1952, served as an alternate delegate to the Democratic National Convention.
