The Association of College Honor Societies ("ACHS"), founded in 1925, is a predominantly American organization that serves a number of functions with respect to national collegiate and post-graduate honor societies. In particular, it is a certifying body for such organizations, facilitates communications between them, and provides both scholarships and an outlet for publication for outstanding members.

The ACHS was formed in 1925, in response to concerns about the unregulated nature of honor societies. Four organizations were represented at a preliminary meeting held on October 2, 1925. They were Alpha Omega Alpha, the Order of the Coif, Phi Beta Kappa, and Sigma Xi. Two other organizations, Phi Kappa Phi and Gamma Sigma Delta , sent word of their interest, although they were unable to attend.

Currently, more than 70 such organizations are currently affiliated with the ACHS.
