The term Mini-Estrella ( Spanish for "Mini-Star") is used in lucha libre to describe a division of short professional wrestlers or luchadors, some of whom have dwarfism. The Mexican Mini-Estrellas is comparable to Midget professional wrestling practiced around the world, 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).
Originally the limit for the Mini division was but in recent years wrestlers such as Pequeño Olímpico have worked the Minis division despite being tall. In the formative years of the Mini-Estrellas history they were also referred to as "Micro Luchadors", or "Micro Wrestlers".
