List of Lambda Upsilon Lambda chapters

Lambda Upsilon Lambda or La Unidad Latina has 81 undergraduate chapters and 17 graduate/professional chapters. The first undergraduate chapter was founded in Cornell University on February 19, 1982. Meanwhile, the first graduate/professional chapter was established in Rensselaer Polytechnic Institute on November 14, 1998. The honorary Pi Sigma chapter is reserved for deceased members of the fraternity.

Greek-lettered chapters of Lambda Upsilon Lambda are given names consisting of either one or two Greek letters after successfully transitioning from provisional chapter status. The names are issued in order according to the dates on which the chapters are transitioned from their provisional phase. Alpha is the name given to the founding chapter at Cornell University, followed by Beta at Binghamton University for the second chapter, and so on in the Greek alphabet. Chapters beginning with the Greek letter Gamma are reserved for graduate alumni professional chapters, with the first being the Gamma Alpha chapter based in New York City.

Once the Greek alphabet had been exhausted by using single letters at the undergraduate level except Gamma, two-letter names began to be issued except the combination of Pi Sigma and any combination starting with Gamma, starting with Alpha Alpha, then Alpha Beta, then Alpha Gamma, etc. The honorary Pi Sigma chapter and its Greek letter combination, as a result, is reserved for deceased brothers of Lambda Upsilon Lambda due to it having the same starting letters with the latter two words of the fraternity's motto "La Unidad Para Siempre".
