Nigromante (11 October 1944^[1]–27 April 1962) was an Argentine-bred thoroughbred racehorse and notable sire. He won two legs of the Argentine Triple Crown and was among the leading sires in both Argentina and the United States.

Nigromante was a dark chestnut horse bred by Ernesto Pueyrredón's Haras Chapadmalal.^[1][2] He was very muscular,^[3] with strong hindquarters and a high head,^[2] and he had three white socks.^[4]

Nigromante was a full brother to Niña Bruja,^[4] the first foal of his dam, Niguá. Niña Bruja was a successful racer and was considered the best three-year-old filly in Argentina in 1946.^[3]

Nigromante only raced in the year of 1947, and was successful enough to be considered one of the best of his generation. He won 6 of his 8 starts, including the Gran Premio Polla de Potrillos, Gran Premio Jockey Club, and Gran Premio Montevideo. In both of his two losses, the Gran Premio Nacional and the Gran Premio Carlos Pellegrini, he finished second to Doubtless.^[2][4]

Nigromante won the first leg of the Argentine Triple Crown, the Polla de Potrillos, by 3 lengths in a time of 1:361⁄5 for 1600 meters. He only faced three other horses in the race, having scared away other potential competition.^[5]

Nigromante won his sixth race, the Gran Premio Jockey Club, the second leg of the Argentine Triple Crown. He faced five opponents, and ran in a stalking position behind the fast pace-setter Doubtless. Despite going wide around the turn and being interfered with in the stretch, Nigromante won the race easily by 21⁄2 lengths over Doubtless in a time of 2:014⁄5 for the 2000 meters.^[3]

in the Gran Premio Nacional, which was described as being attended by one of its largest crowds in recent years, Doubtless again took the lead, but set a more reasonable pace than in the Gran Premio Jockey Club. Nigromante entered the stretch 6 lengths behind the leader, and managed to close to within 11⁄2 lengths of Doubtless at the wire, finishing second in his first defeat.^[6]

After retiring from racing, Nigromante entered stud at Haras El Bagual.^[1] In late 1957, Rex Ellsworth purchased Nigromante and had him imported in the United States to stand at his Ellsworth Ranch in California.^[2]

Nigromante was the Champion Sire in Argentina in 1957,^[7] and he finished second in 1958 and third in 1961 on the general sire list.^[8] In the United States, he finished third on the general list in 1963.^[2]

To the end of 1969, Nigromante sired the winners of 439 races in Argentina and the United States.^[4] The Jockey Club credits Nigromantes with siring 171 foals, including 30 stakes winners (17.5%), although the records of his Argentine offspring may be incomplete.^[2]

Nigromante died of a ruptured aorta in April 1962.^[2]
