Ricardo Andrés Lagos Weber (born February 21, 1962), son of former Chilean president Ricardo Lagos, is a politician who served as the Ministry General Secretariat of Government of Chile in the administration of former President Michelle Bachelet after having worked for Bachelet's 2005-2006 campaign.

Due to the constant traveling caused by the exile of his father during the military dictatorship of Augusto Pinochet, Lagos Weber was forced to complete his studies in eight different schools, finishing his secondary education at Colegio San Agustin.

He began work on his doctorate in Economics at the University of Cambridge with a President of the Republic Scholarship (Beca Presidente de la República), which he applied for in 1990, but he returned to Chile to work in the Chilean section of the International Labour Organization (ILO) and did not finish the doctorate program.

[3] In 2000, he traveled with President Lagos to Berlin to act as a panelist at the "Third Way" conference, speaking for Chile and his father's administration.

[8] Lagos Weber was a candidate for the congressional elections in December 2005, but withdrew his candidacy in August based on polls that suggested that, even with a 45% showing, he would not secure a seat under Chile's electoral rules.

[11] In late January, 2006, Lagos Weber was named Ministry General Secretariat of Government, essentially the presidential spokesman, by President Michelle Bachelet, and he took office on March 11.
