Steve McClure, born 25 July 1970, is a British rock climber and climbing author, who is widely regarded as Britain's leading and most important sport climber for a period that extends for over two decades, starting from the late 1990s. In 2017, he created Rainman, Britain's first-ever 9b (5.

15b) sport route, and by that stage was responsible for developing the majority of routes graded 9a (5.14d) and above in Britain. Although mainly known for sport climbing, McClure has also been one of the most successful British traditional climbers, and British onsight climbers (in both sport climbing and traditional climbing formats).
