Peter James Winterbottom MBE (born 31 May 1960 in Otley, West Yorkshire), is a former England rugby union footballer who played as an openside flanker.
He made his England debut on 2 January 1982 against Australia, and his final appearance on 20 March 1993 against Ireland.
He was selected on two British and Irish Lions tours in 1983 and 1993, both to New Zealand, where he impressed the locals with his fine play, albeit on losing sides.
He was the second England player to reach 50 caps, after Rory Underwood, and was inducted onto the Twickenham "Wall of Fame" in November 2005.
Winterbottom is the uncle of Swiss-born James Leuzinger, who represented Great Britain at the 2006 Winter Olympics.
