Phi Tau (ΦΤ) is a coeducational fraternity at Dartmouth College in Hanover, New Hampshire, USA. Founded in 1905 as the Tau chapter of Phi Sigma Kappa, the organization separated from the national fraternity in 1956 over a dispute regarding the segregationist membership policies of the national organization. The fraternity renamed itself Phi Tau Fraternity, and in 1972 became the first fraternity at Dartmouth to admit women student members. Today, Phi Tau Coeducational Fraternity is one of only three remaining, officially recognized coeducational Greek organizations on the Dartmouth College campus.
