The Order Sons of Italy in America (OSIA) is the largest and longest-established national organization for men and women of Italian heritage in the United States.
Established in 1905 as a mutual aid society for the early Italian immigrants, today OSIA has more than 600,000 members and supporters and a network of more than 700 chapters coast to coast, making it the leading service and advocacy organization for the nation's estimated 26 million people of Italian descent.
Its missions include encouraging the study of Italian language and culture in American schools and universities; preserving Italian American traditions, culture, history and heritage; and promoting closer cultural relations between the United States and Italy.
The Sons of Italy Foundation (SIF) is a private, philanthropic institution, established by OSIA in 1959. To date, the SIF has given more than $93 million to scholarships, medical research, cultural preservation, disaster relief, and other projects.
The Commission for Social Justice (CSJ) is the anti-defamation arm of OSIA. The CSJ is committed to fighting racism, prejudice, and the stereotyping of all races, religions and cultures.
OSIA's national headquarters is in Washington, D.C., near Capitol Hill and the various congressional office buildings.
