Sir William Joshua Goulding, 1st Baronet (7 March 1856 – 12 July 1925) was an Anglo-Irish business magnate, Irish unionist politician and rugby player.
In 1875 Goulding's father employed John Pentland Mahaffy to take his son on a Grand Tour to Italy and Greece, for part of which they travelled with Oscar Wilde.
He was made a member of the Privy Council of Ireland in the 1917 Birthday Honours, and was subsequently appointed by the British government to join the Irish Convention of 1917–1918.
In March 1921 he led a deputation of southern unionists formed to persuade Roman Catholic bishops to act as intermediaries between Sinn Féin and the British government.
That month he also founded the Irish Businessmen's Conciliation Committee alongside Andrew Jameson, which aimed to galvanise the support of businesses against the partition of Ireland.
