Andrew Clifford Warrington (born 10 June 1976) is an English former professional footballer and the current first team goalkeeping coach at Derby County.

An injury to York City's then first choice goalkeeper, Dean Kiely, meant Warrington was required to make his debut for the Minstermen in the return fixture at Bootham Crescent.

While York City eventually lost the game 1–3, to a Manchester United team containing Schmeichel, Beckham, Giggs, Scholes, Cole and Cantona amongst others,[3] it was enough to see the Yorkshire side into the next round.

The following season saw Warrington involved again as York City pulled off another League Cup shock with a 3–2 victory over Everton at Bootham Crescent,[4] after the first game at Goodison Park ended in a 1–1 draw.

He was part of the team that won the 2003 Football Conference Playoff Final[6] held at the Britannia Stadium, after saving two crucial penalty kicks in the shoot-out against Chester City to decide the semi-final.

On 2 May 2013 Rotherham manager Steve Evans announced the club had decided to release the fans' favourite[20] with immediate effect, describing it as "as tough a decision as I have had to make in my managerial career"[21] On 27 July 2013, Warrington signed a contract with Northern Premier League outfit Buxton for the 2013–14 season,[22] after featuring for The Bucks during their pre-season fixtures.

[24] Manager Paul Hurst confirmed on Grimsby's 'Mariners World' on 16 July 2015, that Warrington would also be No 2 while youth Callum Bastock continues his rehabilitation from a knee cruciate ligament injury and deputise for first choice goalkeeper James McKeown.
