USS Knave (AM-256) was an Admirable-class minesweeper built for the United States Navy during World War II. She served in the Atlantic during World War II and was decommissioned in May 1946 and placed in reserve. While she remained in reserve, Knave was reclassified as MSF-256 in February 1955 but never reactivated. In October 1962, she was sold to the Mexican Navy and renamed ARM DM-13. In 1994 she was renamed ARM Cadete Juan Escutia (C56). She was stricken in 2000, but her ultimate fate is not reported in secondary sources.
