Thomas Dreßen is a retired German World Cup alpine ski racer. He specializes in the speed events of downhill and super-G. Dreßen made his World Cup debut in February 2015 at the Saalbach downhill. He made his first podium in December 2017 in the downhill at Beaver Creek and his first win came the following month at Kitzbühel.

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.
