Letterform Archive is a non-profit museum and special collections library in San Francisco, California dedicated to collecting materials on the history of lettering, typography, printing, and graphic design. It is curated by graphic designer Rob Saunders, who founded the museum with his private collection of "books, periodicals, maquettes, posters, and other ephemera" in 2014. The museum opened in February 2015 with 15,000 items. It moved to a larger space in 2020. Visits can be scheduled by appointment. The Archive presented the “Without Type: The Dynamism of Handmade Letters” exhibit with the San Francisco Center for the Book from January 22 to April 3, 2016.
