Juan Martín Hernández is an Argentine retired rugby union player. A mainstay of the Argentina national team The Pumas. He played for the club Toulon in the French Top 14 competition. His 2010 move to Racing brought him back to the city where he had begun his professional career in 2003 with Stade Français. He has also played in the South African Currie Cup with the Sharks, and was slated to play with the Sharks in Super Rugby in 2010, but suffered a back injury that knocked him out of the Super Rugby season. Hernández is a "utility back" capable of playing at fly-half, centre, or fullback, though he generally prefers fly-half.
