Sir Frank Chalton Francis KCB (5 October 1901 – 15 September 1988) was an English academic librarian and curator. Almost all his working life was at the British Museum, first as an Assistant Keeper in the Department of Printed Books, and later as Secretary of the museum, Keeper of Printed Books and, from 1959 to 1968, Director and Principal Librarian of the museum.
As director, Francis worked to modernise and expand the museum, and his ideas contributed to the establishment of a separate British Library after his retirement. He was a well-known bibliographer, lecturing in the subject at University College, London, and serving as secretary, and later president, of the Bibliographical Society. He was one of the pioneers of computerised bibliography for libraries.
