The Collared Peccary (Dicotyles tajacu) is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus Dicotyles. They are commonly referred to as javelina, saíno, or báquiro, although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as quenk.

Although somewhat related to true Old World pigs and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus Pecari, studies in 2020 placed in the genus Dicotyles, based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists. However, the IUCN still places it in the genus Pecari.
