Peter Fill is a former World Cup alpine ski racer from northern Italy. Born in Brixen, South Tyrol, he formerly competed in all disciplines, and later focused on the speed events of downhill, super-G, and combined. Fill won the World Cup season title in downhill in 2016 and in 2017, and the combined title in 2018.

Downhill is a form of alpine skiing competition. Whereas the other alpine skiing events emphasize turning and technique, downhill emphasizes "the six components of technique, courage, speed, risk, physical condition and judgement", according to the FIS "International Ski Competition Rules (ICR)". Speeds of up to 130 km/h (81 mph) are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag and increase speed.
