Shianne edged out u-17 South African Team ringball players Alison Allan and Verochka Els for the award.
This follows her election as the European and African 2013 Female Skier of the Year.
She is ranked as the second best junior and fifth best skier overall in the world.
Furthermore, the former Woodlands Primary School pupil was selected for the South African Junior and Open Team that participated in the European and African Federation Championships in October 2013 in Kimberly.
She took first position in tricks and second in slalom, whilst the team finished first overall in the team competition.
“It was really exciting,” she said at the time, referring to her achievement.
“I’ve been working hard to become world champion, and now I’m halfway there by becoming the European champion.”
Shianne could not be reached for comment amid her Junior Sportswoman of the Year crowning, as she was at the world championships in Australia early this month.
