Marcos Alberto Angeleri (born 7 April 1983) is an Argentine footballer who plays for Uruguayan club Club Nacional de Football as a central defender.
Born in La Plata, Buenos Aires Province, Angeleri made his first appearance for Estudiantes in 2002. He played in the championship decider for the Apertura 2006 title, and in 2008 was called by Diego Maradona to the Argentina national football team.
Angeleri is mostly deployed as a wingback on the right, where he is noted for his aggressive defense and solid transition play along the right flank. Under coach Diego Simeone he also played as a libero. His freedom to join the attack was increased after the arrival of Leonardo Astrada as coach in mid-2008, causing Angeleri to be noticed by Maradona and by South American sports journalists, who voted Angeleri in a top-ten place in the 2008 edition of the South American Footballer of the Year award.
