Fadrique Ignacio Iglesias Mendizábal (born October 12, 1980 in Cochabamba) is a Bolivian middle distance runner, who specialized in the 800 metres.

[1] He set both a national record and a personal best time of 1:48.16 by winning the silver medal for the 800 m at the 2006 Ibero-American Championships in Ponce, Puerto Rico.

[2] Iglesias made his official debut for the 2004 Summer Olympics in Athens, where he competed in the men's 800 m. He finished eighth in the first heat of the event by two thirds of a second (0.66) behind Azerbaijan's Alibay Shukurov, with a time of 1:51.87.

At the 2008 Summer Olympics, Iglesias ran in the sixth heat of the men's 800 m against seven other athletes, including Czech Republic's Jakub Holuša and Morocco's Amine Laalou, both of whom were heavy favorites of this event.

Iglesias, however, failed to advance into the semi-finals, as he placed fifty-third overall, and was ranked farther below two mandatory slots for the next round.
