Rebecca Hourwich Reyher (1897–1987) was an American writer, lecturer, and suffragist. She was the head of the New York and Boston offices of the National Woman's Party.

In 1917 she married Ferdinand Reyher, and in 1919 they had a daughter called Faith. They divorced in 1934.

Between 1935 and 1937 she worked as a regional director of the Works Progress Administration for New York and New England, and from 1937 to 1939 as assistant to the director of the WPA’s Information and Motion Pictures Service.

In 1937 she left America as part of the "Flying Caravan" of delegates of the People's Mandate Committee, which went to South America and was meant to urge ratification of the peace treaties adopted at the Buenos Aires Conference of 1936, and to create support for a petition demanding that governments reject war.

In the 1940s she produced a morning radio series, Have Fun with Your Children, on New York station WNYC. She was a grandmother by this time and was known as Becky Reyher. She also published two children's books, Babies and Puppies Are Fun! (1944) and My Mother is the Most Beautiful Woman in the World (1945), and edited two other books, The Stork Run, a Collection of Baby Cartoons (1944) and Babies Keep Coming, An Anthology (1947). She also published numerous magazine articles throughout her career.

In the 1960s he was a lecturer on the topic of women and Africa at schools, including the New School for Social Research and New York University.
