Elaine Black Yoneda (September 4, 1906 – May 29, 1988) was an American labor and civil rights activist, member of the Communist Party[1] and candidate for political office in California.

[4][8] After relocating to San Francisco in 1933, Yoneda continued her activities in the civil rights, labor, and union movements, and also joined the Communist Party and worked for the ILD as a district secretary.

[9] Yoneda's work with the ILD included supporting striking agricultural workers and visiting prisoners such as Tom Mooney and others who had been arrested under the Criminal Syndicalism laws.

Yoneda herself was arrested a number of times, including in Dolores Park, San Francisco, for participating in a rally against the Criminal Syndicalism laws in March 1935.

Yoneda became known as the “Red Angel” for her work in defending union members and labor demonstrators in the San Francisco waterfront and General Strike of 1934.

She ran for the San Francisco Board of Supervisors in 1939 on a platform of free day care, low cost housing, and civil rights.

[3][4][12][9] After the bombing of Pearl Harbor in 1941, Yoneda's husband and the couple's two-year-old son, Tommy, were excluded from the West Coast and required to be incarcerated at a concentration camp in Manzanar, California.
