Cooke, from Wick, Vale of Glamorgan, also enjoyed a memorable year, starting Great Britain's gold medal rush at the Olympics when she won the women's road race.
She also became world road race champion in Italy a month later with another gutsy sprint finish.
Other honours went to David Brailsford, who masterminded Team GB's cycling success in Beijing, who is appointed CBE while swimming coaches Billy Pye and Dave Haller become MBEs.
Cyclist Simon Richardson from Porthcawl, who was seriously injured in a cycling accident in 2001 and won two gold medals at the Paralympics, becomes an MBE.
Olympic gold medal-winning cyclist Geraint Thomas is also an MBE, as is golden Olympic rower Tom James.
Wales is well represented in other walks of life, with conductor Owain Arwel Hughes becoming a CBE for services to music and charity.
Owain Arwel Hughes has worked with the BBC National Orchestra of Wales
His career has spanned 40 years and he has conducted and recorded with many leading orchestras, including the Royal Philharmonic Orchestra of which he is principal associate conductor.
Dee Edwards from Caernarfon, Gwynedd, co-founder of Mothers Against Murder and Aggression, becomes an MBE for services to vulnerable people.
William Dickson from Chepstow, director of the Welsh Centre for Burns and Plastic Surgery at Morriston Hospital, Swansea, is appointed MBE for services to medicine.
Mr Dickson and his team were closely involved in the role the centre played following the Port Talbot Corus explosion in 2001.
He also operated on badly-burned five-year-old girl Sidra Afzal in 2007, implanting a gel-filled balloon under her scalp to allow new skin and hair to grow.
Other MBEs reflected the tapestry of community life, including Samuel Evans, of Pennal near Machynlleth, who is founder member of the Meirionnydd National Vintage Tractor and Engine Club and Raymond Smith, who retired as a senior carpenter at the National History Museum at St Fagans near Cardiff.
