Ross Turnbull (born 4 January 1985) is an English football goalkeeper who plays for Chelsea after signing for them on 2 July 2009.

On 2 July 2009, Turnbull joined Chelsea on a free transfer, signing a four-year contract. On the 4 July 2009 Turnbull announced that he would not sit by as a permanent second place keeper to regular starting Goalkeeper Petr Cech and that he would fight for his own first team place. Ross was left out of Chelsea's community shield game against Manchester United, sparking rumours that Ross was signed as a third choice goalkeeper. However, he was on the bench for Chelsea's first game of the 2009-2010 season against Hull City at Stamford Bridge, which finished 2-1 in favour of Chelsea. This sparked another rumour that manager Carlo Ancelotti is happy with both keepers on being a second choice in giving them each a game on the bench and a call up when needed. Turnbull had a Chelsea reserves debut to forget when he made a series of blunders as the Blues lost 4-0 to Aston Villa. He made his first team debut against Bolton Wanderers in the League Cup coming for injured Henrique Hilario, a game which Chelsea won 4-0. He made his first start in the UEFA Champions League against APOEL Nicosia.
