The winner will be announced on Blue Peter on Thursday 10 December (5.30pm on CBBC). They will also take part in the BBC Sports Personality of the Year live show on 20 December on BBC One.
Every year many talented young sportspeople are nominated for the award, sometimes called YSPOTY, by different sports governing bodies via the Youth Sport Trust.
A special panel then choose the finalists.
This year it was the turn of Olympic diver Tom Daley (who has himself won the title three times), Blue Peter presenter Richie Driss, and Blue Peter viewer Lucy Tristram.
Lucy won a competition to join the panel as a Blue Peter Young Judge after applying for a Blue Peter Sport badge.
They were also joined by 2018 Young Sports Personality of the Year winner and Paralympic medallist Kare Adenegan, Leeds Rhinos director of rugby Kevin Sinfield and Radio 1 presenter Adele Roberts.
