Rob Warner (16 November 1970) was an English professional biker downhill.
Before turning professional in 1993, Warner worked for 6 months at Rover's Oxford factory on a production line building the Rover 800 series car. After racing for Saracen with teammate Steve Peat and then MBUK, he signed for Giant Bicycles Downhill Team, and remained with them until the end of 2016.
He subsequently joined Commencal Bikes in 2017 in the role of brand ambassador.
In 1996 he became the first ever British rider to win a round of the UCI Mountain Bike World Cup by taking a historic victory at Kaprun in Austria. According to Warner, in a video streamed to Pinkbike on June 2, 2014 titled The Lost Rob Warner Story, he actually won the Kaprun World Cup with an STI that he picked up at Les Gets a week earlier. He became the UK national champion in 1997, 1998 and finally in 2001.
After his competitive career, he is a regular fixture as a commentator in world cup races.
