Alpha Psi Lambda National, Inc. (ΑΨΛ) is a co-educational, Latino-oriented fraternity which began in 1985 at Ohio State University.

Alpha Psi Lambda was founded in May 1984, when Josue Cruz, an assistant vice provost for the Office of Minority Affairs at Ohio State University, aided a group of students in researching existing Greek Letter Organizations with the idea of forming a Latino-affinity group.

Rather than join an existing group, the students decided to establish a new on-campus organization, co-educational in nature and with a Latino affinity.
