Karl Darlow (born 8 October 1990) is a professional footballer who plays as a goalkeeper for EFL Championship club Leeds United.

Darlow signed a new four-year contract on 23 August 2013 and established himself as manager Billy Davies' first-choice goalkeeper despite the summer arrival of Dorus de Vries.

[16][17] On 9 August 2014, Darlow signed a long-term contract with Premier League club Newcastle United for an undisclosed fee.

[20] He made his Premier League debut on 28 December 2015, against West Bromwich Albion as a late inclusion, after regular keeper Rob Elliot was forced to pull out due to illness; the Magpies lost the game 1–0 after Darlow let Darren Fletcher's header slip through his hands.

[21] Following a season-ending injury to Elliot while away on international duty, Darlow was forced to take over in net for Newcastle's final eight matches as they attempted to avoid relegation.

[25] Darlow played in Newcastle's first two League Cup matches against Cheltenham Town and Wolverhampton Wanderers, keeping clean sheets in both.

[32] The terms on his loan meant that Darlow could not be recalled despite Newcastle facing a goalkeeping shortage ahead of the 2023 EFL Cup final on 26 February.

[39] Darlow was called up to the Wales senior squad for the first time for the Nations League matches against Turkey and Montenegro in September 2024.
