The yellow goatfish (Mulloidichthys martinicus), also known as yellowsaddle, is a species of goatfish native to the Atlantic Ocean around the coasts of Africa and the Americas. This species can reach a length of 39.4 centimetres (15.5 in) TL, but most reach lengths only around 28 centimetres (11 in). They are of minor importance to local commercial fisheries, even though they have been reported to carry the ciguatera toxin.
