William Kelleher (born 20 January 1968) is an Irish politician who has been a Member of the European Parliament (MEP) from Ireland for the South constituency since July 2019.

[3] He was an unsuccessful candidate at the 1992 general election, missing out by 25 votes,[3] but was nominated by the Taoiseach Albert Reynolds to the 20th Seanad in 1993.

[6] In January 2006, Kelleher became embroiled in a minor controversy when he was caught speeding outside Cashel, County Tipperary on his way to Leinster House in Dublin.

The misdemeanour was ironic, for it came in a week when the government was coming under fire over poor road safety statistics.

"[14] In March 2022, Kelleher said that Sinn Féin's decision to remove thousands of media statements shows that its position on "major issues have always been wrong.

"[15] In April 2022, he asked Kerry Group (a company in which he owned shares) to cease operations in Russia.

[16] Kerry Group decided to suspend their operations in Russia and Belarus, which was welcomed by Kelleher.
