Matrimony's Speed Limit is a 1913 silent short film produced and directed by pioneering female film maker Alice Guy-Blaché. It was produced by Solax Studios when it and many other early film studios in America's first motion picture industry were based in Fort Lee, New Jersey, at the beginning of the 20th century. It is one of only about 150 films surviving out of the more than one thousand produced and/or directed by Guy-Blaché.

The film's preservation, along with a few others by Guy-Blaché, was initially financed by the Women's Film Preservation Fund upon its inauguration in 1995. It was selected to the National Film Registry by the Library of Congress in 2003.In December 2018, Kino Lorber released a six-disc box, Pioneers: First Women Filmmakers, made in cooperation with the Library of Congress, the British Film Institute and others. The first disc of the set is devoted to the films of Guy-Blaché and includes Matrimony's Speed Limit (1913).
