General elections were held in Mexico on Sunday, 2 July 2000. Voters went to the polls to elect a new president to serve a single six-year term, replacing President Ernesto Zedillo Ponce de León, who was ineligible for re-election under the 1917 Constitution. The election system ran under plurality voting; 500 members of the Chamber of Deputies for three-year terms and 128 members of the Senate for six-year terms.
