London 2012 gold medallists Jade Jones and Mark Colbourne will be among more than 40 Welsh stars parading on the steps of the Senedd this weekend.
The Welsh government is also encouraging Games Makers who took part in either the Olympic or Paralympic Games to wear their uniforms to the event on Friday evening.
Jones, from Flint, won Great Britain’s first ever Olympic gold in taekwondo, while Paralympic cyclist Colbourne, from Tredegar, picked up three medals, including gold in the C1 individual pursuit.
Other medallists who will be met by First Minister Carwyn Jones and Presiding Officer Rosemary Butler include Tom James (rowing, gold), Fred Evans (boxing, silver) and Aled Davies, who set off on a memorable lap of honour after winning gold in the F42 discus.
Josie Pearson, who broke the world record three times to win the F51/52/53 discus – Great Britain’s 10th and final Paralympic athletics gold – is also set to attend.
The evening is set to begin at 4.30pm with performers from Wales’s cultural Olympiad, including 19-year-old clarinet player Lloyd Coleman, Abergavenny Borough Brass Band and Ebbw Vale Male Choir, entertaining the crowds.
The public will be able to show their appreciation to the athletes from about 6pm.
