Calvinistic Methodists were born out of the 18th-century Welsh Methodist revival and survive as a body of Christians now forming the Presbyterian Church of Wales. Calvinistic Methodism became a major denomination in Wales, growing rapidly in the 19th century, and taking a leadership role in the Welsh Religious Revival of 1904-5.

Calvinistic Methodism claims to be the only denomination in Wales to be of purely Welsh origin, owing no influence in its formation to Scottish Presbyterianism. It is also the only denomination to make use of the title Calvinistic (after John Calvin) in its name. In 18th-century England Calvinistic Methodism was represented by the followers of George Whitefield as opposed to those of John and Charles Wesley, although all the early Methodists in England and Wales worked together, regardless of Calvinist or Arminian (or Wesleyan) theology, for many years. With Calvinistic Methodists being absorbed into Presbyterianism, Methodism became defined by its adherence to Wesleyan-Arminian theology.
