In an incredible campaign, Launchbury has established himself as a regular for both Wasps and England.
Launchbury featured in every game of the Six Nations for England, while also racking up 13 appearances for Wasps in the Aviva Premiership.
And after being named the best player aged 23 or under, he couldn't hide his joy at the recognition.
He said: "I am delighted, it is a good reflection on me and how Wasps have done this year as a team so it is good to get a bit of recognition like this.
"The Aviva Premiership seems to be getting a lot younger, and there is a lot of good talent around so to come out on the top of that pile is a massive honour for me and I am delighted.
"I've really enjoyed my rugby this year, I have had an injury-free year and loved every minute of it.
"I have hopefully kept my form going throughout the year and playing for England and getting that first cap was a massive thing for me then coming back to Wasps - results haven't gone our way of late - but we have still been playing well and it is a season to be proud of."
