Octagoncito is a Mexican Luchador enmascarado, or masked professional wrestler, who works in the Mini-Estrellas ("Mini-Stars") division on the Mexican Independent circuit. He is the first wrestler to work as Octagoncito, with Asistencia Asesoría y Administración (AAA) giving the same ring character to a second Octagoncito when the original one left the promotion in 1995. Octagoncito's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans. In addition to working for AAA Octagoncito has also worked for Consejo Mundial de Lucha Libre (CMLL), Lucha Libre USA, World Wrestling Federation (WWE), World Championship Wrestling (WCW) New Japan Pro-Wrestling (NJPW) and a slew of smaller wrestling promotions. Working in the Mini division does not necessarily mean that Octagoncito has dwarfism, as short wrestlers can also work in the "Mini" division.

The term Mini-Estrella is used in lucha libre to describe a division of short professional wrestlers or luchadors, some of whom have dwarfism. The Mexican Mini-Estrellas are comparable to midget wrestlers who compete internationally, but with the notable exception that some of the Mini-Estrellas do not have dwarfism but are simply short. Some Mini-Estrellas have later on moved on to work as regular sized competitors. The Mini-Estrellas have been featured in several promotions outside Mexico, most notably World Wrestling Entertainment (WWE) and Total Nonstop Action Wrestling (TNA).
