List of Lambda Chi Alpha chapters

The following is a list of the chapters and colonies of the Lambda Chi Alpha Fraternity (ΛΧΑ), an international men's collegiate fraternity, ordered by name; activating the column headings will sort the list by installation year, institution, location, or status.

Broadly, a chapter is an organization of members of the fraternity attached to an institution or geographic location which has received a charter authorizing it to operate as the local unit of Lambda Chi Alpha. A colony is a local group which is being organized or reorganized and has not yet met the standards for a charter. Most newly issued charters go to colonies established by the General Fraternity, although the majority of charters were issued to petitioning local societies. In the early days of the fraternity, founder Warren A. Cole issued charters to so-called picked delegations, groups of correspondents who were interested in forming a fraternity chapter but who had not yet organized themselves. Additionally, in 1939, Lambda Chi Alpha merged with Theta Kappa Nu and absorbed 28 active chapters, plus 7 on campuses where Lambda Chi Alpha was already represented.

Lambda Chi Alpha chapters are known as subordinate Zetas, or simply Zetas. Thus, the Alpha chapter at Boston is referred to as Alpha Zeta. Zetas are identified by Greek letters in a unique "scrambled alphabet" naming scheme.

At the fraternity's inception, founder Warren A. Cole assigned Greek letters to petitioning groups that had not yet been chartered. Predictably, not all of these groups were chartered. As a result, the first seven chapters were designated Α, Γ, Ε, Ζ, Ι, Λ, and Β, in that order. John E. Mason created a twenty-four word mnemonic device with words representing each Greek letter once— the first seven words were in the order that the chapters were already named.

Therefore, the chapters are named in the order: Α, Γ, Ε, Ζ, Ι, Λ, Β, Σ, Φ, Δ, Π, Ο, Μ, Τ, Η, Θ, Υ, Ξ, Χ, Ω, Κ, Ν, Ρ, Ψ. After the twenty-fourth chapter, the sequence was continued with a prefix and hyphen (Α-Α, Α-Γ, Α-Ε, ... Γ-Α, Γ-Γ, Γ-Ε, ... Ε-A, etc.)
