Jorge Batlle Colorado Tabaré Vázquez Broad Front General elections were held in Uruguay on 31 October, alongside a constitutional referendum.

Broad Front leader Tabaré Vázquez was elected president on his third attempt after his party won just over 50% of the vote, enough for him to win the presidency in a single round.

To date, this is the only time that a presidential election has been decided without a runoff since the two-round system was introduced in 1999.

The Broad Front also won majorities in the Chamber of Deputies and the Senate.

The Uruguayan presidential primaries were held on 27 June 2004, to choose single candidates for every party.
