Alpha Pi Sigma

Alpha Pi Sigma Sorority Incorporated (ΑΠΣ) is a multicultural Latina-based sorority founded in 1990 at San Diego State University. It was created to bring together and support the Latina women but is open to non-Latinas. The sorority has seventeen chapters in five states.

Thirteen Latina women established Alpha Pi Sigma on March 10, 1990, at San Diego State University. They saw the need to unite and support Latina women on university campuses.

The sorority's founders established six purposes that define the organization. The chapters carry out these purposes, including academic excellence, leadership development, cultural awareness, unity and friendship, empowerment, and community service. However, academic excellence is the sorority's primary value, along with community service.

The sorority is a member of the National Association of Latino Fraternal Organizations (NALFO) and holds a strict anti-hazing policy.

Both active sisters and alumnae are encouraged to raise funds to support the sorority's national philanthropy. Chapters also select their philanthropies and volunteer in the Latino community. Some examples of the Alpha Pi Sigma efforts are American Cancer Society, autism awareness, lunch distribution, heart disease awareness, a Tijuana-based orphanage, and Relay for Life.

There are seventeen active chapters of Alpha Pi Sigma in the United States, most in California. Active chapters are indicated in bold. Inactive chapters are indicated in italic.
