Jessica-Jane Applegate, Josef Craig and Rebecca Tunney have been named as the three contenders for the Young Sports Personality of the Year award.
The trio have been selected from an original shortlist of 10.
Artistic gymnast Tunney was the youngest athlete to compete at London 2012 at the age of 15, while swimmers Applegate and Craig both won gold medals at the Paralympic Games.
The winner will be announced during Sunday's live show on BBC One.
Presented by Sue Barker, Gary Lineker and Clare Balding, Sports Personality of the Year will be broadcast live on BBC One, BBC One HD and BBC Radio 5 live from 19:30 GMT.
A capacity crowd of 15,000 at the ExCel in London will make it the biggest show in the event's 59-year history.
Those nominated for the Young Sports Personality award had to be aged 16 or under on 1 January 2012.
Last year's winner was golfer Lauren Taylor. She claimed the award after becoming the youngest winner of the Ladies' British Open Amateur Championship, which she took in June 2011.
Applegate is also 16 years old. The Norfolk-born swimmer won gold at the Paralympics in London after setting a new Games record in the 200m Freestyle S14 final.
Fifteen-year-old swimmer Craig was crowned the youngest Paralympic gold medallist at London 2012, after smashing his own world record in the 400m freestyle S7 final.
Sixteen-year-old Tunney, the youngest member to represent Team GB at the London 2012 Olympics, is a British all-round gymnastics champion.
