The side lost only four games throughout the year – by one, two, three and four points respectively.
The club’s Chief Executive Sean McGuire said that the moment was a proud one for the club, as they became the first rugby league winners of the award since Wigan in 1994.
"It was a proud moment for everyone involved with the club to see us officially recognised as the country's highest sporting achievers of 2006”, McGuire said.
I'm particularly delighted for the players and coaching staff, especially head coach Daniel Anderson, but this award is really for the fans who have continued to support us in magnificent style."
Saints have already been recognised within the rugby league world for their achievements – full-back Paul Wellens claimed the Man of Steel award, the Harry Sunderland Trophy and the Rugby League Writers’ award.
St Helens had to beat off competition from double-winning Sussex CCC and Europe’s victorious Ryder Cup team.
