Alejandro René Eleodoro Guillier Álvarez (born 5 March 1953) is a Chilean sociologist, television and radio journalist, and independent politician.

[1] Guillier ran in the New Majority primary for the 2017 election and was the coalition's standard bearer in the 2017 presidential elections to replace term-limited president Michelle Bachelet.

Among others, he faced former PPD president Ricardo Lagos before the latter's withdrawal from the contest.

Polling showed him to be competitive against Chile Vamos candidate Sebastián Piñera, although his support slipped in the run up to the election and after a series of splits between the traditional left coalition block.

[2] Gullier is a freemason[3] and a member of the Valparaíso Parliamentary Lodge since 2014.
