Sir John Dashwood-King, 3rd Baronet (4 August 1716 – 6 December 1793) was an English country gentleman. Born John Dashwood, he adopted the additional surname of King by the terms of his uncle Dr. John King's will.
The son of Sir Francis Dashwood, 1st Baronet by his third wife, Mary King, he was the half-brother of the infamous Sir Francis Dashwood, 2nd Baronet. He was a member of the Hellfire Club which his brother had founded.
His principal interests lay in his lands in Wales and Lincolnshire which he had inherited from his maternal uncles. From 1753 until 1761, he served as Member of Parliament for the pocket borough of Bishop's Castle, controlled by his brother-in-law John Walcott. In 1761, he married Sarah Moore (d. 9 April 1777), by whom he had eight children, of whom four survived him:
He served as High Sheriff of Montgomeryshire in 1777. He inherited West Wycombe Park and the baronetcy in 1781, upon the death of his half-brother, but made no significant changes there before his death in 1793.
