James Bert Sonnier (born October 1, 1938 in Church Point, Louisiana)[1] is a retired trainer of thoroughbred racehorses.
A Cajun, at age eight he began galloping horses and learned about competitive racing at area bush tracks.
During his career, he conditioned a number of very good horses including the injury-prone Meadowlake, sire of the great Meadow Star, the 1990 American Champion Two-Year-Old Filly and winner of the Breeders' Cup Juvenile Fillies.
Sonnier's best runner was Nodouble who earned back-to-back American Champion Older Male Horse honors in 1969 and 1970.
Sonnier retired having won 1,531 races, saddling his last runner on February 10, 2003 at Gulfstream Park in Hallandale Beach, Florida.
