World super middleweight champion Joe Calzaghe has been expressing his delight at being appointed a CBE.
"For the first time in my life I was knocked out," he said.
There were OBEs for leading cricket official David Morgan and writer Russell T Davies, who is credited with resurrecting Doctor Who for the BBC.
They are joined by community champions, volunteers and academics from across Wales who have been honoured.
Boxer Calzaghe, from Newbridge, was named in the Queen's birthday honours list as recognition for his decade-long reign at the top of his sport.
He had previously appointed an MBE in 2003 but said he news of his further award - for services to sport and voluntary services in Wales - had come completely out of the blue.
"It will probably sink in a few years' time when I finish and realise what I've achieved and what I've done," he told BBC Wales.
Ex-chairman of the England and Wales Cricket Board (ECB) David Morgan receives his OBE as prepares to take over as president of the International Cricket Council (ICC) on 4 July, the most powerful job in world cricket.
Also a former chairman of Glamorgan, Tredegar-born Mr Morgan, 70, said: "I am obviously delighted to be honoured in this way but I have been fortunate at the ECB to have had the support of both its administration and its board members.
"And with that support we have achieved a great deal within the game of cricket in England and Wales from the playground right up to the Test arena.

"This award is for all the hard work that everyone has put in."
Swansea-born writer Russell T Davies was honoured for services to drama and said he was "chuffed".
"I'm delighted to accept, and I hope it does the whole industry a bit of good, for the writing of television drama to be recognised."
BBC Wales controller Menna Richards said: "I cannot think of anyone more deserving of such recognition than Russell.
"He is simply an amazingly talented person who has transformed Saturday evening TV for millions of people through Doctor Who."
Davies announced he was quitting from his role as executive producer and lead writer on Doctor Who last month.
He is also known for other dramas, including Torchwood for the BBC, The Sarah Jane Adventures for CBBC, along with Casanova and Queer as Folk.
Elsewhere, honours were given to those who have served their community or have been recognised for their work.
Peter Backhouse, who has been a scout leader in Cardiff for 30 years, becomes an MBE and said he accepted the honour "on behalf of of all these wonderful people in scouting and in youth work who give up all their time".
Scouting is a wonderful family. We as leaders have been privileged to work with wonderful children
Mr Backhouse, who is group scout leader of First Llanedeyrn Christchurch, said he was "shocked and overwhelmed" to be honoured.
"It's an amazing situation. I'm extremely proud," he said.
"Scouting is a wonderful family. We as leaders have been privileged to work with wonderful children. It's all about having an adventure."
The father-of-three, 62, has helped run the beavers, cubs and scouts since 1978, ever since his eldest son Andrew, 39, came home and said his cub group needed a new Akela.
"Hopefully scouting is the same now as it was then," he added.
"I've got the children of the children now and it's all still fun and exciting."
Meanwhile, Elizabeth Murphy, who founded the Beacon of Hope charity in 2000, has received an MBE for services to the community in Ceredigion.
The charity has two offices in Aberystwyth and Cardigan and helps people with terminal and life-limiting illnesses.
"I must confess I was staggered when I found out I'd been awarded the MBE," said Mrs Murphy.
"It's a great honour and I was prepared to accept it to further raise the profile of the charity."
Stephen Gamgee, who is chief executive of The Wallich homelessness charity in Cardiff, was appointed an MBE for for services to homeless people.
Mr Gamgee, 57, from Penarth, who has worked in the homelessness field for 25 years, said: "I'm quite humbled by it actually. My wife was very proud.
"I have a lot of people working with me on this. It's their award as much as mine. I think they will probably take the same view as me that it is good for the organisation to get recognition like this."
Also honoured was lifeboat coxswain Robert Wright, from Pwllheli, who has been given an MBE for voluntary service to maritime safety.
