Washington University has eleven fraternities and nine sororities on campus. Approximately 45% of women and 30% of men participate in Greek life, totaling 35% of the student body. In 2012, the chapter of Sigma Alpha Mu was closed following violations of drug and alcohol policies among students. In 2020, a large number of Greek life members, primarily from sororities, permanently detached themselves from their chapters as a result of perceived systemic oppression, racism, and sexism. Many students are now calling for the total abolition of Greek Life on campus.

Washington University offers several leadership development programs, scholarships, and civic engagement opportunities for students to get involved with the larger community.
