The 1943 All-Ireland Senior Hurling Championship was the 57th staging of the All-Ireland Senior Hurling Championship, the Gaelic Athletic Association's premier inter-county hurling tournament. The championship began on 2 May 1943 and ended on 5 September 1943.
The championship was won by Cork who secured the title following a 5-16 to 0-4 defeat of Antrim in the All-Ireland final.[1] This was their 14th All-Ireland title.
Cork were also the defending champions and retained the title for the second successive year to become the fourth team to win the three in-a-row.
Eight teams contested the Leinster championship, with Meath and Wicklow returning after absences. Six teams contested the Munster championship, with Kerry fielding a team for the first time after a long absence from the senior ranks. Galway, who faced no competition in their own province, entered the championship at the All-Ireland semi-final stage. The Ulster champions were permitted to enter the All-Ireland series for the first time.
