The 2019 County Championship, known for sponsorship reasons as the 2019 Specsavers County Championship, was the 120th cricket County Championship season. As in 2018, Division One had eight teams and Division Two had ten teams. The first round of matches began on 5 April and the final round of matches ended on 26 September. Surrey were the defending champions. At the end of the 2019 season only one team was relegated with three promoted. Therefore, from 2020 onwards, Division One would feature ten teams and Division Two would feature eight.
