Zeta Delta Xi (ΖΔΞ or Zete) is a local, co-educational fraternity at Brown University in Providence, Rhode Island. It traces its origins to 1852 as the Epsilon chapter of the all-male national fraternity Zeta Psi. In 1982, the Epsilon chapter decided to admit women as brothers. This led to the chapter's disassociation from Zeta Psi in 1986, and the birth of Zeta Delta Xi on 24 January 1987. A shortened version of its name, "Zete", is commonly used to refer to the fraternity or a member.
