Luis Ángel González Macchi (born December 13, 1947) is a Paraguayan politician.

As the president of Paraguay's legislature, González succeeded to the office of president on March 29, 1999 following the assassination six days earlier of the vice-president, Luis María Argaña, and the subsequent resignation of President Raúl Cubas Grau among accusations that the assassination was linked to Cubas's political party.

As president, González attempted to create a coalition government to spur cooperation within Paraguay and repair the economy which had been damaged by the political crisis. This coalition did not last long, as the Authentic Radical Liberal Party left it in 2000, leaving González without a majority in the legislature. González became ever more unpopular as the economy sagged further and found passing legislation difficult because few legislators would vote on bills that González pushed for. There was a coup attempt in 2000 and an impeachment attempt in 2001, though both failed. González was able to hold on to his presidency until the elections of 2003, which Nicanor Duarte Frutos won. González left office on August 15, 2003.
