Carlos Santos (born October 1, 1955 in Ceiba, Puerto Rico) is a former boxer from Puerto Rico, who represented his native country as an amateur at the 1976 Summer Olympics in Montreal, Quebec, Canada. There he was eliminated in the quarterfinals. Santos was involved both in the first and the fourth world title bouts involving two Puerto Rican boxers in history. It has been suggested that Santos was not born in Ceiba but in the San Juan area named "Santurce", but it is widely believed that Santos is a Ceiba native.
