The 2020 All-Ireland Under-20 Hurling Championship was the second staging of the All-Ireland Under-20 Championship and the 57th staging overall of a hurling championship for players between the minor and senior grades. The championship was scheduled to begin in May 2020, however, it was postponed indefinitely due to the impact of the COVID-19 pandemic on Gaelic games. The championship eventually began on 19 October 2020 and, after being suspended once again, ended on 10 July 2021. Tipperary entered the championship as the defending champions in search of a third successive title, however, they were beaten by Cork in the Munster final. Kerry fielded a team in the Munster Championship for the first time since 2005. On 10 July 2021, Cork won the championship following a 2-19 to 1-18 defeat of Dublin in the All-Ireland final at UPMC Nowlan Park. This was a record 12th All-Ireland title overall and their first title since 1998. Dublin's Liam Murphy was the championship's top scorer with 0-37. (en)
