Boxer Joe Calzaghe and two former England rugby union captains head the list of sporting names in the Queen's Birthday Honours list.
Undefeated world super-middleweight champion Calzaghe, who was already an MBE, receives a CBE for services to sport and voluntary services in Wales.
Lawrence Dallaglio and Bill Beaumont receive an OBE and CBE respectively for services to rugby and charity.
And Northern Ireland striker David Healy has received an MBE.
Calzaghe, 36, is unbeaten in 45 professional fights, including 21 world title defences, and in his most recent bout he beat the legendary Bernard Hopkins in his light-heavyweight debut.
"For the first time in my life I was knocked out," said Calzaghe.
Joe Calzaghe won the BBC Sports Personality award in 2007
"It's unbelievable when I think back to when I was a kid that one day I would have achieved so much through boxing, and my teachers laughed at me when I said I was going to be a boxer."
Beaumont, the vice-chairman of the International Rugby Board, was recognised for his work with rugby's Wooden Spoon charity which helps disadvantaged children.
"I was fortunate enough to receive an OBE for playing the game in 1982, and now 26 years later to get this award for other things which I have managed to achieve makes you feel very humble," he said.
Healy's 13 goals in the Euro 2008 qualifying games is a record
Fulham striker Healy, at 28 the youngest person on the honours list, is Northern Ireland's record goalscorer and was also recognised for his work with the George Best Memorial Trust.
"I've been to Buckingham Palace before to see the changing of the guard as a tourist," said Healy.
"But to go there as the guest of the Queen will be amazing. I'm already nervous about it."
Dallaglio, 35, retired at the end of last season, having spent the whole of his playing career with Wasps.
During that time he won 85 England caps, a World Cup-winner's medal, a Grand Slam, five English titles, two Heineken Cups and was picked for three Lions tours.
He was awarded an MBE in 2003 for his exploits at the World Cup, where he was the only England player to play every minute of every game
Other notable sportsmen and women to receive the MBE include four-times world touring cars champion Andy Priaulx, for services to sport and the community in Guernsey, former West Brom footballer Cyrille Regis, and Arsenal Ladies' players Kelly Smith and Julie Fleeting.
"It is quite a surprise to receive an envelope with the royal logo on," said Priaulx.
"I was really taken aback and very honoured to read they wanted to bestow the MBE on me.
Priaulx has had stamps made in his honour in Guernsey
"I love my racing and am proud to carry the flags of both Guernsey and the UK on my car and overalls, so recognition of this sort is something really special."
Fleeting, who has scored 103 goals in 104 games for Scotland, was also taken aback by her honour.
"It's quite a shock but I'm absolutely thrilled and hopefully it can do a lot for women's football, the fact we are getting recognition," she said.
Former chairman of the England and Wales Cricket Board David Morgan receives an OBE, as does former chief executive of British Gymnastics Alan Somerville.
And John Surtees, the only man in history to be crowned world champion in both Formula One and motorcycling, also received an OBE.
Morgan said his honour was a reward from the team effort made by those around him.
"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."
