She beat out Lena Willikens, TNGHT and The Chemical Brothers for the honour.
The award is chosen by a panel of dance music professionals (which, this year, included Paul Woolford). Rebelle's mix originally aired in February, and it will air again on the morning of December 21st to celebrate her award.
The London DJ won out over the final shortlist of TNGHT, Lena Willikens and The Chemical Brothers. Other recent winners include HAAi, Helena Hauff, Midland, Ben Klock and Caribou.
