The 24-year-old scooped the RaboDirect PRO12 Players' Player of the Year award at Sunday night's ceremony at the Lyceum Theatre in Edinburgh.
Players and coaches from across the competition gathered in Scotland to see Biggar, who was also named in the Team of the Year, handed the prize.
Biggar has racked up 219 points in the RaboDirect PRO12 this season - more than anyone else - and was voted the league's standout player by his peers.
His efforts could not prevent Ospreys from missing out on a playoff spot however as in-form Glasgow Warriors pushed them out of the running in the final reckoning.
"I'm hugely, hugely proud," he said. "When you get voted for by your peers, you ask professional sportsmen and they will say the same - it means an awful lot more coming from fellow players.
"I'm hugely honoured just to play against some of the players we play against, let alone be competing for awards with them.
"I think the season has gone reasonably well. I don't think anyone goes through a season 100 per cent, without any faults - I have certainly got lots of faults - but where I maybe improved a little bit is if you make some errors or do something bad it is about binning that, moving on and hopefully trying to contribute more to your team.
"It has been hugely frustrating (this season). It has been one of those where we haven't gained any momentum through the season.
"It has been a couple of victories here and a couple of losses there - we haven't put a run together and you look at Glasgow, who are probably the form side, and they have got seven or eight victories on the bounce now.
"They are absolutely flying going into the playoffs and we haven't achieved that. Ultimately we have fallen a bit short, which is hugely disappointing, but I think the future is bright for this club.
"It is hard to watch when you have had a chance to be there. We will certainly be watching two good games with four very good sides in them."
