John Philip Kemble was a British actor. He was born into a theatrical family as the eldest son of Roger Kemble, actor-manager of a touring troupe. His elder sister Sarah Siddons achieved fame with him on the stage of the Theatre Royal, Drury Lane. His other siblings, Charles Kemble, Stephen Kemble, Ann Hatton, and Elizabeth Whitlock, also enjoyed success on the stage.

The Warwickshire Company of Comedians, also known as Mr Ward's Company of Comedians and after 1767 as Mr Kemble's Company of Comedians, was a theatre company established by John Ward in Birmingham, England in the 1740s, touring throughout the West Midlands region and surrounding counties over subsequent decades. Unusual in the 18th century as a provincial company producing performances to London tastes and standards, it is particularly notable as the origin of the Kemble family theatrical dynasty, which was to dominate the English stage in the late-18th and early 19th centuries. Sarah Siddons and John Philip Kemble in particular, who were Ward's grandchildren and whose careers began in the company, were the leading actress and actor of their time, and are still considered among the greatest performers in English theatrical history.
