The left-handed opener’s 12,472 Test runs is the most by any English batter, placing him fifth in the all-time list, but after retiring from international duty in 2018, he carried on playing for Essex.
His contract at the county expired at the conclusion of the domestic season last month and the 38-year-old, part of Essex’s County Championship-winning side in 2019, has elected against seeking a renewal.
‘It is not easy to say goodbye,’ Cook said in a statement. ‘For more than two decades, cricket has been so much more than my job. It is the right time for this part of my life to come to an end.
‘I have always given absolutely everything I possibly have to be the best player I could be, but now I want to make way for the new generation to take over.
‘From the eight-year-old boy who first played for Wickham Bishops Under 11s to now, I end with a strange feeling of sadness mixed with pride. Although, above all, I am incredibly happy.’
Essex head coach Anthony McGrath had hoped ‘we’ll see him for a bit longer’ as speculation swirled about Cook’s future after the Chelmsford club finished runners-up to Surrey in the championship.
But Cook’s decision to retire ends a remarkable career which began in 2003, impressing enough early on to earn the first of 161 Test caps three years later against India in Nagpur, making a ton on debut.
He went on to amass another 32 Test centuries – an England record – and was part of Ashes series wins in 2009, 2010/11, 2013 and 2015, captaining them in the latter two. His 766 runs in the 2010/11 series saw him crowned player of the series and helped England seal a first win Down Under since 1986/87.
Cook won 24 of his 59 Tests as England captain between 2010 and 2016 and skippered the ODI side between 2010 and 2014 before being unceremoniously axed just months before the World Cup the following year.
He bowed out of England duty with a hundred against India at the Kia Oval in September 2018 and was given a knighthood for services to cricket a few months later in the New Year Honours List.
