Tenacious (1954–1967) was an American Thoroughbred racehorse who was one of the most popular ever to compete in New Orleans, Louisiana.
In 1966, Fair Grounds Race Course inaugurated the Tenacious Handicap in his honor and on his death in 1967, a memorial plaque was installed in the track's infield and following its creation in 1971, he was inducted in the Fair Grounds Hall of Fame.
Out of the mare Dorothy B. Jr., Tenacious was sired by Challedon, the 1939 American Horse of the Year and U.S.
Trained by John Theall, for the majority of his important wins Tenacious was by ridden by Cajun jockey Ray Broussard.
