Kappa Alpha Psi (ΚΑΨ) is a collegiate Greek-letter fraternity with a predominantly African-American membership. Since the fraternity's founding on January 5, 1911 at Indiana University Bloomington, the fraternity has never limited membership based on color, creed or national origin. The fraternity has over 150,000 members with 721 undergraduate and alumni chapters in every state of the United States, and international chapters in the United Kingdom, Germany, Korea, Japan, United States Virgin Islands, Nigeria, and South Africa.

The president of the national fraternity is known as the Grand Polemarch, who assigns a Province Polemarch for each of the twelve provinces (districts/regions) of the nation. The fraternity has many notable members recognized as leaders in the arts, athletics, business, civil rights, education, government, and science sectors at the local, national and international level. The Kappa Alpha Psi Journal is the official magazine of the fraternity since 1914. The Journal is published four times a year in February, April, October and December. Frank M. Summers was the magazine's first editor and later on became the Fourteenth Grand Polemarch. The current editor of the magazine is Dr. Keflyn X. Reed.
