Roberto Raúl Iglesias (born 25 February 1951) is an Argentine Radical Civic Union (UCR) politician, a former leader of the party and formerly a deputy and governor of Mendoza Province.

Iglesias was born in Mendoza, Argentina, and enrolled at the local campus of the National Technological University, earning a degree in construction engineering.

In December 2005, Iglesias succeeded Ángel Rozas as president of the national committee of the Radical Civic Union, effectively leader of the party.

[1] Iglesias had supported fellow UCR member, Julio Cobos, to succeed him as governor in 2003, but they subsequently fell out in a high-profile manner.

Iglesias has accepted the request of Morales to plan together the future of the UCR, including to consider an alliance with the centre-left and a way to accommodate those Radicals who have hitherto backed Kirchnerism in the Plural Consensus.
