List of Trine University fraternities and sororities

Fraternities and sororities have maintained a visible presence on the Trine University campus for 100 years. The campus hosts ten honor societies that recognize scholastic achievement, complimenting 13 active undergraduate social fraternities and sororities. Local societies had been predominant during the earlier, non-accredited era of campus growth, but beginning in 1947, national fraternities and then sororities colonized and now make up the majority of chapters. Tri-State's first men's social fraternity, Sigma Mu Sigma formed in 1921, and its first women's social sorority, Sigma Alpha Gamma (local) formed in 1926.

As of 2018, 26% of male and 19% of female undergraduates are involved in these groups.
