Sarah Pratt Carr (1850–1935) was an American writer and Unitarian minister whose life and work reflected the expansion and development of the American West. Born Sarah Amelia Pratt in Freeport, Maine, to Louisa and Robert Henry Pratt, she eventually relocated westward. In 1872, she married Byron Oscar Carr in Carlin, Nevada. She later pursued a religious calling and was ordained as a Unitarian minister in Lemoore, California, in 1896, subsequently working as a missionary across the state.
Alongside her ministerial duties, Carr developed a career as an author. Her most prominent literary contribution is her 1907 historical novel, The Iron Way: A Tale of the Builders of the West, which focused on the construction of the Central Pacific Railroad. In addition to her historical fiction, Carr published several children's books during the 1910s, demonstrating her versatility as a writer.
Carr also collaborated closely with her daughter, the composer Mary Carr Moore. She authored the libretto for Moore's 1911 opera, Narcissa, securing her place in early twentieth-century American opera history. Carr spent her final years in California, where she died in Los Angeles in late 1935.
