John Vanderbank (9 September 1694 – 23 December 1739) was a leading English portrait painter who enjoyed a high reputation during the last decade of King George I's reign and remained in high fashion in the first decade of King George II's reign. George Vertue's opinion was that only intemperance and extravagance prevented Vanderbank from being the greatest portraitist of his generation, his lifestyle bringing him into repeated financial difficulties and leading to an early death at the age of only 45.
