General elections were held in Uruguay on 31 October 1999, alongside a double referendum, with a second round of the presidential election on 28 November. The elections were the first in Uruguay since World War I that were not dominated by the Colorado Party and the National Party. The Broad Front had begun gaining popularity in 1994, and had become a key player in Uruguayan politics by 1999.

The Colorado Party is a liberal political party in Uruguay.
