Guadalupe Ontiveros (née Moreno; September 17, 1942 – July 26, 2012) was an American actress best known for portraying Rosalita in The Goonies, and Yolanda Saldívar in the film Selena.

During a period of dissatisfaction with her career as a social worker, Ontiveros was trying to decide whether to go back to school for a nursing degree when she saw an article about a need for local film extras.

Ontiveros said in multiple interviews that she accepted the role even before seeing the script, solely on the basis of being asked to play a character who was not defined by Hispanic ethnicity.

During the series, she participated with Esai Morales, Tony Plana, Yvonne DeLaRosa, JC Gonzalez, Raymond Cruz and Ana Villafañe.

Her performance received excellent reviews and earned Ontiveros and her co-star a Special Jury Prize at the prestigious Sundance Film Festival.

Ontiveros had a recurring role in the 2004–05 season of American prime time soap opera series Desperate Housewives as Juanita Solis, Gabrielle's suspicious mother-in-law.

In 2004, Ontiveros also began a role as Abuela Elena, the grandmother of the title characters in the animated PBS children's series Maya & Miguel.
