Stephen Philip Cummings is an English former racing cyclist, who rode professionally between 2005 and 2019 for the Landbouwkrediet–Colnago, Discovery Channel, Barloworld, Team Sky, BMC Racing Team and Team Dimension Data squads, and rode for Great Britain at the Summer Olympic Games, the UCI Road World Championships, and the UCI Track Cycling World Championships.

U.S. Postal Service Pro Cycling Team was a United States-based professional road bicycle racing team. On June 15, 2004, the Discovery Channel signed a deal to become sponsor of the team for the 2004–2007 seasons and its name changed to Discovery Channel Pro Cycling Team. From 2005 until 2007, the team was one of the 20 teams that competed in the new UCI ProTour. As part of the sponsorship deal, Lance Armstrong, the team's undisputed leader, provided on-air appearances for the Discovery Networks TV channels. The deal did not affect the rights of secondary sponsor OLN, later known as NBCSN in the US, to air major cycling events such as the Tour de France, although the two channels are competitors.
