The Butler Memorial Headquarters Building is located in Indianapolis, Indiana. Completed in 1971, it is located on a road with eight other fraternity and sorority headquarters (prior to this, the fraternity was headquartered in New York city). The building was financed with a bequest from Lester E. Cox, a University of Pennsylvania chapter alumnus who left half his estate to the fraternity. It is named in honor of Wilford A. Butler, who served as the fraternity's executive director from 1963 to 1987.
