The Heart of Youth is a lost[1] 1919 American silent comedy film directed by Robert G. Vignola and written by Beulah Marie Dix.

The film stars Lila Lee, Tom Forman, Buster Irving, Charles Ogle, Fanny Midgley, Guy Oliver, and Lydia Knott.

[2][3] As described in a film magazine,[4] Calvin Prendergast (Oliver) and Os Whipple (Ogle), small town neighbors, quarrel over a strip of land on which there is a spring to which both claim ownership.

Josephine Darchat (Lee), granddaughter of Calvin, and Russ Prendergast, son of Os, are much attracted to each other although the old men object.

Calvin and Os arrive back in town, and each man's anger is aroused by reports of activities of the other's family.
