Treviso rugby team were founded in 1932. The club won its first honour when they took the 1952 Italian premiership. Benetton Treviso won its first Italian Cup in 1970, and in 1978 won the Italian premiership once again. The year after Benetton became the main sponsor, and the name of the team became "Benetton Rugby Treviso". Treviso won the domestic premiership in 1983, then again in 1989, and in the 1992 season.
Rugby turned professional after 1995. Benetton Treviso dominated the Italian league from 1997 until 2010, winning the championship 10 times (1997, 1998, 1999, 2001, 2003, 2004, 2006, 2007, 2009 and 2010) during those 14 seasons, and twice finishing second. They also won the Italian Cup in 1998.
Benetton Treviso has competed in the Heineken Cup competition almost every year since the competition began in 1995 along with the professional era. Benetton Treviso competed in the inaugural 1995-96 Heineken Cup, winning one game and losing one. The following season they played four matches, winning one game. In the 1998–99 Heineken Cup they won three games. Benetton Treviso spent the 2000–01 and 2002–03 seasons in the European Challenge Cup, but have appeared in the Heineken Cup in each season since then. They won half of their games during the 2004–05 Heineken Cup, but won only one match in the following four seasons (at Newport Gwent Dragons in 2007). In the 2009–10 Heineken Cup opener they defeated reigning French Top 14 champions Perpignan 9–8 in Treviso.
Following the 2009-10 season Treviso left the Italian domestic competition, and in 2010-11 was one of two Italian teams to join the Celtic League to play against clubs from Ireland, Wales and Scotland. Both Italian teams were guaranteed places annually into the Heineken Cup, which had previously been awarded to the two top teams in the domestic Italian National Championship of Excellence. An agreement had been reached in early March 2010 to allow two Italian teams a place in the Celtic League. In 2010 it was proposed that Aironi and a new team Praetorians Roma would join, but Treviso were nominated instead. Treviso and a combination of Duchi Nord-Ovest rugby clubs could not agree to form one regional representative club and lost out in the first round of bidding. However, Pretorians Roma failed to satisfy financial criteria, and Treviso instead joined the Celtic League (renamed the Pro12). Treviso finished their first two season in the Pro12 (2010-2011 & 2011-2012) in 10th place, while in the 2012-2013 season they finished 7th.
