The Welsh Methodist revival was an evangelical revival that revitalised Christianity in Wales during the 18th century. Methodist preachers such as Daniel Rowland, William Williams and Howell Harris were heavily influential in the movement. The revival led eventually to the establishment of the Welsh Calvinistic Methodists as a denomination and it also revitalised older dissenting churches.

Daniel Rowland served as an Evangelist and early on as an Anglican curate. He was one of the foremost figures in the Welsh Calvinistic Methodist revival, along with the evangelist Howell Harris and the hymnist William Williams. For 55 years Daniel Rowland was one of the leading evangelists in Wales.
