Alessandro Troncon (born 6 September 1973 in Treviso) is a former Italian rugby union player.

The veteran scrum-half made his Italy debut against Spain (62–15) in 1994[2] and has played alongside fly-half Diego Dominguez on more than 50 occasions.

[citation needed] In 2007 Troncon was named man of the match as he scored a try in Italy's first overseas victory at Murrayfield against Scotland (37–17) in the 2007 Six Nations.

Troncon was in the Italian squad at the 2007 World Cup, during which he made his 100th appearance for his country, in a pool-match game against Portugal (31–5).

In doing this, he became only the seventh rugby union player to reach 100 caps, after George Gregan, Stephen Larkham, David Campese, Jason Leonard, Fabien Pelous, Philippe Sella and one game before Gareth Thomas.
