Charles Jervas (also Jarvis and Jervis; c. 1675 – 2 November 1739) was an Irish portrait painter, translator, and art collector of the early 18th century.

After selling a series of small copies of the Raphael Cartoons circa 1698 to Dr. George Clarke of All Souls College, Oxford, the following year he travelled to Paris and Rome (while financially supported by Clarke and others) remaining there for most of the decade before returning to London in 1709 where he found success as a portrait painter.

Jervas was first to provide an introduction to the novel including a critical analysis of previous translations of Don Quixote.

It has been highly praised as the most accurate translation of the novel up to that time, but also strongly criticised for being stiff and humourless, although it went through many printings during the 19th century.

As principal portraitist to the King of England, Jervas was known for his vanity and luck, as mentioned in the Imperial Biographical Dictionary, "He married a widow with $20,000; and his natural self-conceit was greatly encouraged by his intimate friend [Alexander] Pope, who has written an epistle full of silly flattery."
