Rosita is a Hispanic Muppet character on the children's television series Sesame Street. Fluent in both English and Spanish, she is the first regular bilingual Muppet on the show. Rosita comes from Mexico and likes to play the guitar.

Her full name, Rosita, La Monstrua de las Cuevas, is a rarely used reference to the fact that Rosita is a fruit bat hence the Spanish "Monster of the Caves".

Rosita was introduced to the series in 1993, when the series explored what was "around the corner" of Sesame Street.

Rosita is performed by Carmen Osbahr , who originally worked on Mexico's Plaza Sesamo.
