Justin Winsor (1831–1897) was an American historian and librarian. Born in Boston, he became superintendent of the Boston Public Library and in 1877 librarian of Harvard University, and he was a founder and first president of the American Library Association.

His work combined wide bibliographical knowledge with careful attention to maps and original sources.
