These are the only awards voted for by the players themselves, with votes collected from the entire professional player group across the country.
Jonathan Sexton, Chairman of IRUPA, said: "Winning an IRUPA award, which is voted for by the players is a huge mark of respect for any rugby player.
"The Hibernia College Player of the Year award is particularly well regarded by the players, as it rewards consistency and skill at the highest level."
The award is one of seven which will be announced at the annual IRUPA Awards ceremony on Wednesday, May 8 at Dublin's Burlington Hotel.
Among the other awards is the Nevin Spence Young Player of the Year, contested this year by a feast of talented young players including Connacht's Robbie Henshaw, Leinster's Ian Madigan, also nominated in 2012, and Luke Marshall from Ulster.
The Volkswagen Try of the Year includes Craig Gilroy's try against Argentina in the November internationals, Iain Henderson's effort against Saracens in Ulster's Heineken Cup quarter-final and Simon Zebo gets a second nomination for his try against Wales in the RBS 6 Nations.
2013 is the second year of the Hibernia College Medal for Excellence which will be awarded to the individual who demonstrates exceptional commitment to the game both on and off field.
This is a player who matches their playing and training with team support, studies, work, mentoring, charity and community involvement.
Players across the provinces voted for Leinster's Isaac Boss, Ulster's Chris Henry and retiring Munster prop Marcus Horan, a former Chairman of IRUPA.
Ulster's Nigel Brady, Munster's Billy Holland and Michael Swift of Connacht have been shortlisted for the IRUPA O2 Unsung Hero award.
