The 2020 Cork Premier Intermediate Hurling Championship was the 17th staging of the Cork Premier Intermediate Hurling Championship since its establishment by the Cork County Board in 2004. The draw for the group stage placings took place on 19 November 2019. The championship was scheduled to begin in April 2020, however, it was postponed indefinitely due to the coronavirus pandemic in Ireland. The championship began on 1 August 2020 and ended on 3 October 2020.
On 3 October 2020, Blarney won the championship after a 1-20 to 0-15 win over Castlelyons in the final at Páirc UàChaoimh. This was their second championship title overall and their first title since 2008.
Blarney's Mark Coleman was the championship's top scorer with 1-50.
On 26 March 2019, three championship proposals were circulated to Cork club delegates. A core element running through all three proposals, put together by the Cork GAA games workgroup, was that there be a group stage of 12 teams and straight relegation and promotion. On 2 April 2019, a majority of 136 club delegates voted for Option A which would see one round of games played in April and two more in August â all with county players available.
