Héctor Martín Desvaux (born 4 February 1980 in Santa Fe) is an Argentine football defender currently playing for Central Córdoba.
Desvaux started his career with Unión de Santa Fe in 2001 while the team played in the Primera División Argentina. In 2003, his club was relegated from the Argentine Primera but Desvaux stayed with them.
During the 2005–06 season, Desvaux played for Ben Hur, but returned to Unión the following season. In 2007, he returned to the top flight of Argentine football, signing for Gimnasia de Jujuy on loan. At the end of the 2007–08 season Gimnasia defeated Unión, Desvaux's former team, in the playoff to avoid relegation and the defender played both home and away games (along goalkeeper Nereo Fernández, another former Unión player loaned to Gimnasia).
In 2010, Desvaux joined Chilean side Santiago Wanderers.
