Samuel Pike (1717?–1773) was a British clergyman and a member of a religious movement known as Sandemanians.

The Glasites or Glassites were a small Christian church founded in about 1730 in Scotland by John Glas. Glas's faith, as part of the First Great Awakening, was spread by his son-in-law Robert Sandeman into England and America, where the members were called Sandemanians.
