The trophy was presented to para-athlete Kare in front of thousands at the SSE Arena, Wembley. Being named Young Sports Personality of the Year comes after a successful year for Kare which saw her become T34 100m WPA European champion, winning her first gold medal in senior competition, and taking silver in the T34 800m.
She also set a new T34 100m world record at the London Anniversary Games - where she became the first female T34 athlete to complete the race in under 17 seconds.
To top off an incredible season, she beat long-time rival Hannah Cockroft for the first time in a championship race at the Diamond League in July.
The Young Sports Personality of the Year title was hotly contested this year with ten talented youngsters in the running for the prestigious award.
The ten were Kare Adenegan, Freya Anderson (swimming), James Bowen (horse racing), Max Burgin (athletics), Jack Draper (tennis), Georgia-Mae Fenton (gymnastics), Anna Hursey (table tennis), Georgia Roche (rugby league), Ryan Sessegnon (football) and Maisie Summers-Newton (para-swimming) with Freya and James making up the top three alongside Kare.
Kare follows in the footsteps of past winners and sporting superstars like Ellie Simmonds, Wayne Rooney, Tom Daley, Andy Murray, Ellie Downie, Eleanor Robinson and Phil Foden.
Kare will attend BBC Sports Personality of the Year in December when the prestigious awards show will take place in Birmingham at the Genting Arena.
