Scott Robert Mills (born 28 March 1973) is a British radio DJ, television presenter and occasional actor, best known for presenting The Scott Mills Show on BBC Radio 1. As of the 2011 Contest, Mills commentates for the semi-finals of the Eurovision Song Contest on BBC Three with fellow BBC Radio DJ Sara Cox.

Mills began his career at the age of 16 as a DJ on his local Hampshire commercial radio station, Power FM, after barraging the station with demo tapes. Mills was given an opportunity to present a week worth of shows, and based on the success of this, he was immediately offered the 'graveyard slot' of 1:00 a.m. – 6:00 a.m. (six nights a week), making him the youngest permanent presenter on the mainstream commercial radio. Mills' popularity led to a quick move to the coveted late afternoon 'drive time'.

Mills moved from Power FM to GWR FM, staying with the station for two years, before joining Piccadilly Key 103 in Manchester where he again moved quickly from the late night slot to the mid-morning show. In 1995, Mills began to work for the new London station Heart 106.2.
