The Ñeta Association (Asociación Pro-Derechos del Confinado, "Association for Prisoners' Rights", Asociación Ñeta, or simply Ñeta) is the name of a gang that began in the Puerto Rico prison system and spread to the United States mainland. Although Puerto Rico has many small street gangs claiming its poorer neighborhoods, Ñetas is by far the largest and most dominant, controlling the illegal drug trade in the island's prison system.
