The Phi Beta Sigma fraternity is founded by African-American students at Howard University in Washington D.C., United States.

Phi Beta Sigma Fraternity, Inc. (ΦΒΣ) is a historically African American fraternity. It was founded at Howard University in Washington, D.C. in 1914. The fraternity's founders, A. Langston Taylor, Leonard F. Morse, and Charles I. Brown, wanted to organize a Greek letter fraternity that would exemplify the ideals of Brotherhood, Scholarship and Service while taking an inclusive perspective to serve the community as opposed to having an exclusive purpose. The Fraternity was built on the principles of brotherhood, Scholarship, and Service, with the goal of creating an organization that would serve both college campuses and surrounding communities. The fraternity exceeded the prevailing models of Black Greek-Letter fraternal organizations by being the first to establish alumni chapters, youth mentoring clubs, a federal credit union, chapters in Africa, and a collegiate chapter outside of the United States. It is the only fraternity to hold a constitutional bond with a historically African-American sorority, Zeta Phi Beta, which was founded on January 16, 1920, at Howard University in Washington, D.C., through the efforts of members of Phi Beta Sigma.
