Henry James Carr (August 16, 1849 – May 21, 1929) was an American librarian. Carr was raised in New Hampshire and Grand Rapids, Michigan. He worked as an accountant and cashier in railway offices from 1867 to 1886. During that time, he studied law at the University of Michigan, gaining admission to the bar in 1879, but he never practiced law. In 1886, Carr was named librarian for the Grand Rapids Public Library, where he worked until 1890 when he was recruited to create a new public library for the residents of Saint Joseph, Missouri. In 1891 he moved to Scranton, Pennsylvania, to assist them in establishing their public library.
