1970 All-Ireland Senior Hurling Championship

The 1970 All-Ireland Senior Hurling Championship was the 84th staging of the All-Ireland Senior Hurling Championship, the Gaelic Athletic Association's premier inter-county hurling tournament. The championship began on 3 May 1970 and ended on 6 September 1970.

Kilkenny were the defending champions but were defeated by Wexford in the Leinster final. Kildare, who won the All-Ireland Intermediate Hurling Championship in 1969, were promoted to the senior championship after a long absence. New York sought entry to the All-Ireland series but their request was denied. Galway left the Munster Championship after ten years of participation and reverted to the old system whereby they enter the championship at the All-Ireland semi-final stage.

The All-Ireland final was played at Croke Park in Dublin on 6 September 1970 between Cork and Wexford, in what was their fourth meeting in the All-Ireland final overall and a first meeting in 14 years. Cork won the match by 6-21 to 5-10 to claim their 21st All-Ireland title overall and a first title in four years.

Cork's Charlie McCarthy was the championship's top scorer with 1-23. Cork's Pat McDonnell was the choice for Texaco Hurler of the Year.

Rule change
As a result of a decision taken at the Gaelic Athletic Association's (GAA) annual congress the previous year, as of 1970 all provincial finals, All-Ireland semi-finals and the All-Ireland final itself were extended to 80 minutes playing time. Prior to this all championship matches were sixty minutes in duration. Lasted until 1974.

Teams
A total of fourteen teams contested the championship, including thirteen teams from the 1969 championship and one new entrant.

The Leinster championship was extended to seven teams as Kildare entered the provincial series of games. They had won the All-Ireland title at intermediate level in 1969 and decided to make the step up to the senior grade.

Galway left the Munster championship where they had been playing since the 1959 championship and returned to the old system whereby they entered the All-Ireland semi-finals.
