"Sí, se puede" is the motto of the United Farm Workers of America, and has since been taken up by other activist groups. UFW co-founder Dolores Huerta created the phrase in 1972 during César Chávez's 25-day fast in Phoenix, Arizona. "Sí se puede" has long been a UFW guiding principle that has inspired the accomplishment of goals. The phrase is a federally registered trademark of the UFW. It has been widely adopted by other labor unions and civil rights organizations, and drew widespread political and media attention as a rallying cry during the U.S. immigration reform protests.

Dolores Clara Fernández Huerta is an American labor leader and civil rights activist who, with Cesar Chavez, is a co-founder of the United Farmworkers Association, which later merged with the Agricultural Workers Organizing Committee to become the United Farm Workers (UFW). Huerta helped organize the Delano grape strike in 1965 in California and was the lead negotiator in the workers' contract that was created after the strike.
