William Augustus Barron (1751–1812) was a British landscape painter.
[3] He was a pupil of William Tomkins and younger brother of Hugh Barron.
He practised as a landscape painter, and also as a drawing master.
His skill upon the violin gained him an introduction to Sir Edward Walpole, who gave him a situation in the exchequer, which in 1808 he still held.
In the print-room of the British Museum, there is a large pen drawing by him of Richmond Bridge in 1778.
