and dozens of club and intramural sports, and many multi-cultural programs and services. More than 94 percent of students are involved in campus activities. Greek organizations Greek life is a popular option at Butler with over 35 percent of undergraduates becoming members of social fraternities or sororities. Fraternities and sororities have long been a part of student life at Butler, with the first fraternity established in 1859, and the first sorority established in 1874. Today, representatives from each of the seven active fraternities make up the Interfraternity Council (IFC), which coordinates men's recruitment and works with the Panhellenic Council to plan all-campus events. The Panhellenic Council has representatives from each of Butler's seven active sororities and women's fraternities.

The sorority had its beginnings on the original Irvington campus of Butler University. While most NPHC undergraduate chapters have citywide memberships with students from more than one university, the Alpha chapter of Sigma Gamma Rho is composed only of Butler students. Part of the original Divine Nine of Black Greek letter organizations, Sigma Gamma Rho is one of two Indiana based historically all-black Greek organizations in the state. Today there is a commemorative stained glass window located just outside the tower room
