Alexander Daniel Hales (আলেকজান্ডার ড্যানিয়েল হেলস) is an English cricketer. He is a right-handed opening batter who represented the England cricket team across all formats and played domestically for Nottinghamshire. He made his One Day International debut against India in August 2014 and his Test cricket debut against South Africa in December 2015. Hales is the first English batter to score a T20I century, and has the highest individual score of an English batter in the format with his 116 not out against Sri Lanka in the 2014 ICC World Twenty20. He is also the first batter to be dismissed for 99 in an ODI and a T20I. Hales was a key member of the England team that won the 2022 T20 World Cup. In August 2023 Hales announced his retirement from international cricket, focusing on domestic and franchise T20 cricket.

Hales was born in Hillingdon and attended both Westbrook Hay School and Chesham High School, now Chesham Grammar School, in Buckinghamshire.

His father Gary broke several local batting records (including 321 not out for Gerrards Cross versus Chalfont St Peter in a limited overs league match) while his grandfather Dennis was a talented tennis player who once forced Rod Laver to five sets at Wimbledon.

In September 2017, Hales, along with teammate Ben Stokes, was charged with bringing the game into disrepute by the England and Wales Cricket Board (ECB). The charge related to an incident that took place outside a Bristol nightclub, in September 2017, several hours after England had played a one-day international against the West Indies at the County Ground in the city. Stokes was charged with affray over the incident by police and the ECB deferred its disciplinary hearing until the legal proceedings had finished.
