Chancellors of the University of Massachusetts Amherst are individuals who serve in the top position of the university. The office, originally known as "President," was changed to "Chancellor" in 1970 following John W. Lederle's resignation and the opening of UMass Boston five years earlier. The title "President of the University of Massachusetts" now refers to the president of the entire five-campus University of Massachusetts system. The current chancellor of the Amherst campus is Javier Reyes. The chancellor resides in Hillside, the campus residence for chancellors.
