Manuel "Pantera" Montero (born November 20, 1991 in Buenos Aires) is a rugby union footballer, who plays for Club Pucará and Argentina on the wing.
Montero switched to rugby from basketball as a teenager, when his best friend Agustín José Fornonzini forced him to do so, claiming he would be an outstanding rugby player. He was selected for the Argentina Under 20's side for the IRB Junior World Cup in 2010, a year later in 2011 he was the standout player for Argentina in the Under 20 World Cup scoring against Italy and setting up a try with a great individual effort. After a spell in the Argentina Sevens side, in 2012 he gained selection for the Pampas XV and made his Pumas debut later that year, scoring a hat trick in his second test against Brazil and scoring 5 tries in his 3 matches. In his first start against a top nation, he scored the match winning try to defeat France in Cordoba.
He was included in Argentina's squad that debuted at the new 2012 Rugby Championship.
Montero is signed to play for Jaguares until 2017.
