Selina Hastings, Countess of Huntingdon was an English Christian and religious leader who played a prominent part in the religious revival of the 18th century and the Methodist movement in England and Wales. She founded an evangelical branch in England and Sierra Leone, known as the Countess of Huntingdon's Connexion.

Methodism, also called the Methodist movement, is a Protestant Christian tradition whose origins, doctrine and practice derive from the life and teachings of John Wesley. George Whitefield and John's brother Charles Wesley were also significant early leaders in the movement. They were named Methodists for "the methodical way in which they carried out their Christian faith". Methodism originated as a revival movement within Anglicanism originating out of the Church of England in the 18th century and became a separate denomination after Wesley's death. The movement spread throughout the British Empire, the United States and beyond because of vigorous missionary work, and today has about 80 million adherents worldwide.
