The Methodist Church in Ireland (Irish: Eaglais Mheitidisteach in Éirinn) is a Wesleyan Methodist church that operates across both Northern Ireland and the Republic of Ireland on an all-Ireland basis. It is the fourth-largest Christian denomination in Northern Ireland. The Irish Methodist Church has close links with the Methodist Church in Britain.

For the year ending 31 December 2012, there were 105 Methodist ministers, 227 local preachers and over six hundred lay people in leadership positions serving over 200 congregations, which combine to form a total community of 49,394 people. In 2018, the numbers of members and wider community role was approximately 50,000. The governing body of the Methodist Church in Ireland is the annual Conference.

Methodism was founded in England by John Wesley and his younger brother Charles Wesley during the 18th century, initially as a revival movement within the Church of England. The spread of Methodism to Ireland was facilitated by English preachers, and the early Irish adherents were nicknamed 'Swaddlers', after John Cennick delivered a sermon in Dublin on "the babe in swaddling clothes" (Luke 2:12). It was John Wesley's twenty-one visits between 1747 and 1789 which were crucial in fostering the Irish Methodist community. He built and opened the first dedicated Methodist chapel in Ireland on Whitefriar Street in Dublin in 1752. By 1789 Methodist membership exceeded 14,000 in Ireland. Irish Methodism initially exerted the most influence among members of the established Church of Ireland and migrant European minorities, such as Moravians, Palatines and Huguenots. There were significantly fewer conversions to Methodism among Irish Catholics.

During the Great Famine, Methodist membership declined significantly from 44,000 in 1844 to 26,000 by 1855; over 15,000 members emigrated during the period from 1840 to 1859.

Irish Methodism experienced a division in 1816 due to disagreements regarding whether Irish preachers were authorised to administer the sacraments. This resulted in the formation of two distinct connexions: the Wesleyan Methodists and the Primitive Methodists. These two bodies reconciled and reunited in 1878, more than fifty years prior to the equivalent reunification in Britain. The all-Ireland denomination has continued despite the political partition of Ireland in 1922.

The church began to ordain women in 1978.

In 1997, Methodist membership was about 18,000. By 2018, there were 50,000 members and adherents across the island.

In 2002 the church signed a covenant with the Anglican Church of Ireland, leading to a closer working relationship.
