Rosa "Rosita" Casagrande is a recurring character in The Loud House, who first appeared in "The Loudest Mission: Relative Chaos", and later a major character in its spin-off The Casagrandes.


Rosa is the wife of Hector, the mother of Carlos and Maria, the mother-in-law of Frida, the former mother-in-law of Arturo and the grandmother of Carlota, CJ, Carl, Carlitos, Bobby, and Ronnie Anne. She is the manager of the Casagrande Apartment building and also the resident cook of the Casagrande family, and has many potions, as well as healing methods.


Rosa is a very caring and loving person, and is always thinking of her loved ones. She is always happy to cook for her family, but can go overboard; if someone simply wants a snack, she will prepare an entire meal for them. When someone eats other snacks than hers, she treats it like treason and disrespect.

She is also vigilant about her loved ones' health, and will always be prepared with any old remedy she knows to make them feel better.

She cares a lot for her family. However her care for family sometimes leads her to paranoia as shown in episodes "The Spies Who Loved Me" and "Away Game". Due to her overprotectiveness she ready to spy on her grandchildren and track them in case something bad happens. She also was afraid that Ronnie and Bobby will permanently move to Arturo.

She is very superstitious as she depends on lucky talismans and assumed that Ronnie Anne was turned into a rat by black magic.

She practices old-school methods of parenting her grandchildren, such as scaring them with scary stories and beating them with a shoe, or "chancla," for misbehaving. Carl is shown to be the prime target of this type of parenting, as he is the most ill-behaved child.


She is a short, rotund Mexican American woman with tan skin, dot eyes, short black hair, rolled into a bun, and golden circular earrings. She wears a navy blue dress, with a white collar, as well as having white on the end of the sleeves, a greenish blue apron, and black shoes.
