With four fixtures staged at Musgrave Park and five at the newly refurbished Thomond Park Stadium, the province have sold over 160,000 tickets for their Magners League games.
With another capacity sell-out crowd expected for their final home game tonight against the Ospreys, Munster's average ticket sales reached almost 18,000, moving the province into the top three, alongside Stade Francais and Toulouse, in terms of support for league rugby throughout Europe.
David Jordan, Director of Celtic Rugby, said: "The success that Munster have experienced on the pitch has been reflected off it with the confirmation that they are the Magners League's best supported team for the 2008/09 campaign.
"The award reflects both the hard work behind the scenes and the fact that Munster's loyal fans are turning out in all weathers to endorse a style of rugby that has seen their team become the Magners League champions this season.
"The refurbishment of Thomond Park Stadium is a magnificent achievement and I'm sure it will provide a fitting backdrop to the presentation of the trophies later this evening. Congratulations must go to everyone concerned with the province."
Stephen Kent, Marketing Director, Wm Magner Ltd added: "We would like to offer our congratulations to everyone at Munster. This award reflects the hard work put in both on and off the field, along with the passion and loyalty of Munster's fantastic fans.
"This award, alongside Munster being crowned Magners League champions, reflects the hunger that exists for the Magners League brand of rugby.
"We look forward to another sell-out crowd at tonight's game, an exciting game of rugby and to celebrating the title with Munster and their fans following the game."
