Jones and the Lady Book Agent is a 1909 American silent comedy film written by Frank E. Woods and directed by D. W. Griffith. Produced by the American Mutoscope and Biograph Company in New York City, the short stars John R. Cumpson, Florence Lawrence, and Flora Finch as the "lady book agent". It is one film in a series of 1908 and 1909 Biograph pictures in which Cumpson and Lawrence performed together as the married couple Mr. and Mrs. Jones. When this comedy was released in May 1909, it was distributed to theaters on a "split reel", which was a single projection reel that accommodated more than one motion picture. It shared its reel with another Biograph comedy short directed by Griffith, The French Duel. The film was released on May 10, 1909 by Biograph Company and was met by positive viewers. The film is presumed lost.

Original contact-print paper rolls of both motion pictures, as well as projectable safety-stock footage of the productions, are preserved in the Library of Congress.
