Omar Fernando Tobio (born October 18, 1989) is an Argentine professional footballer currently playing for Huracan.

Tobio made his debut for Vélez Sársfield on March 1, 2008. In 2009, he was part of the squad that won the Clausura tournament, though he did not play any games. He did however play 8 games in Vélez' following league title, the 2011 Clausura, mainly as a backup for the starting centre backs Sebastián Domínguez and Fernando Ortiz.^[1] He also finished the tournament as a starter, replacing injured Fabián Cubero as a right full back; and played 5 games in the 2011 Copa Libertadores, scoring one goal in the semi-finals against Peñarol.

After Fernando Ortiz's departure from Vélez following the 2011–12 season, Tobio became a regular starter in Vélez's first team, playing alongside Sebastián Domínguez as centre backs, and helping the team obtain the 2012 Inicial league title.

In January 2009, Tobio was called for the Argentina under-20 squad that played the South American Youth Championship in Venezuela. He played all 9 games as the team finished 6th, failing to qualify for the U-20 World Cup.
