Chi Delta Mu (ΧΔΜ) is a professional fraternity for students and graduates in the allied health professions.

[2] The first meeting laying the ground work for the fraternity took place on January 30, 1913, and it was presided over by E. Clayton Terry and Charles Humbert.

The January meeting was attended by twenty-eight students, and several decided to return at a later date to formally establish the details of the new organization.

The purpose of the fraternity was to "unite men of the medical professions of Medicine, Dentistry, and Pharmacy into a closer relationship so that the highest degree of efficiency and scientific ability might be developed."

The pin is rendered in gold, with a rectangle affixed with the Greek letters of the society, ΧΔΜ surrounded by alternating stones in red and blue.
