Delta Mu Delta (ΔΜΔ) is an international honor society that recognizes academic excellence in baccalaureate, master's, and doctorate business administration programs.

Its chapters are only located at institutions that are accredited by the Association of Collegiate Business Schools and Programs.

Delta Mu Delta was founded at New York University on January 16, 1914, by a dean Joseph French Johnson and professors George Burton Hotchkiss, Charles W. Gertstengerg, Edward J. Kilderf, and John R. Weldmon from the university's School of Commerce, Accounts and Finance.

[2] In January 1992, the society signed an exclusive agreement with the Association of Collegiate Business Schools and Programs stating that all future chapters of Delta Mu Delta must be established at ACBSP-accredited colleges and universities.

[1][4] The society's badge is a gold key in the form of the triangular Greek letter Delta.
