A Lover's Oath is a lost 1925 American silent fantasy film directed by Ferdinand P. Earle and featuring Ramon Novarro.

A Lover's Oath is a lost save for a short segment (around thirty seconds[citation needed]) held by the Academy Film Archive; the archive preserved the film in 2009. An additional 135-foot section was apparently discovered and uploaded to YouTube, purportedly by the Academy Film Archive.
