The Red Brangus is an American breed of hybrid beef cattle, with both taurine and indicine genetic heritage.

[5]: 137  In the early 1930s, development of the Brangus taurine-indicine hybrid breed through cross-breeding between American Angus and Brahman stock began in Louisiana.

[5]: 138  The idea was to create a hybrid combining some of the meat qualities and polledness of the Angus with some of the resistance to heat and disease of the Brahman.

[5]: 138 In the 1940s a Texas rancher named Matthew Levi, who had a grey Brahman bull and a herd of black Angus cows, found that matings yielded both black and red calves.

For the international association the animal must be of 5/8 Angus and 3/8 Brahman descent; for the other, it may be any mix of the two breeds, but registration is conditional on inspection.
