Samuel Cautherley (c.1747–1805) was a British stage actor.
Born to the actress Jane Green, he was reputed to be the son of David Garrick, actor-manager at the Theatre Royal, Drury Lane.
Cautherley began appearing there as a child actor.
Sent away to school he quickly returned again to the stage in 1760 and, after another short period away, in 1765.
He played Charles Dudley in Cumberland's The West Indian and appeared in a mixture of lead and supporting roles until falling out with Garrick in 1775, after which he quit the stage.
