Vincentive (foaled 1940)^[1] was an American Thoroughbred racehorse from Maryland who won the 55th running of the Dwyer Stakes at Belmont Park on June 19, 1943. Owned by William Leavitt Brann,^[2] the colt defeated Famous Victory, owned by Mrs. Payne Whitney. Vincentive was ridden by jockey Johnny Gilbert, who weighed 111 pounds. The win was worth $19,600.^[3]

A son of Challenger (Great Britain) and Phenomenon (United States), the thoroughbred attained career earnings of $36,935. In 16 starts he had 5 wins, 2 places, and 4 shows.^[1] He won by seven lengths as a juvenile in the October 10, 1942 Maryland Futurity. The $5,000 race was held at Laurel Park Racecourse. Ridden by George Woolf, Vincentive ran the six furlongs in record time for the stake, 1:11 3/5. This was merely 4/5 of a second behind the track record held by Star Porter. Vincentive earned $4,290.^[2]

In 1943 Vincentive skipped the Kentucky Derby and prepared for the Preakness Stakes. He won a six furlong event at Pimlico Race Course on May 3, 1943, defeating Noonday Sun. In the 53rd running of the Preakness, on May 8, 1943, Vincentive finished a disappointing 3rd to winner Count Fleet and second place Blue Swords. Before 29,381 spectators, Count Fleet's time of 1:57 2/5 did not eclipse the record of 1:56 2/5 set by Riverland in the Dixie Handicap, run at Pimlico a week earlier.^[4]
