Theta Nu Epsilon

Theta Nu Epsilon (ΘΝΕ, commonly known as T.N.E.) was an American sophomore class collegiate society that later became a traditional social fraternity. Founded at Wesleyan University in 1870 as a chapter of Skull and Bones, the society expanded into a new national organization. It accepted members regardless of their fraternity status. It was a member of the National Interfraternity Conference (NIC).

Through various controversies, most chapters of the society went inactive by 1920. It reformed as a social fraternity in 1925 and regained its membership in the NIC. It did not survive World War II, and the society's last official chapter closed in 1942. However, several chapters continued to operated sub rosa.
