Charles Warren (19 March 1764 – 12 August 1829) was an English barrister and politician, judge and amateur cricketer.
A son of Richard Warren, and nephew of John Warren, he was brother to John Warren the Dean of Bangor, Pelham Warren the physician, and Frederick Warren; and so uncle to John's children Sir Charles Warren, and John Warren the mathematician. He was educated at Westminster School and Jesus College, Cambridge, which he entered in 1780, matriculating in 1784, and graduating B.A. in 1785, M.A. in 1788. He was a Fellow of Jesus College, from 1786 to 1813. Entering Lincoln's Inn in 1781, he was called to the bar in 1790. He was elected a Fellow of the Royal Society in 1790.
In 1792, Warren signed a declaration by the Society of the Friends of the People. He was called as a defence witness in the 1798 trial of Sackville Tufton, 9th Earl of Thanet.
An Old Bailey barrister, Warren also took up a bankruptcy commission. He was chancellor to the diocese of Bangor from 1797, for the rest of his life.
Warren was made King's Counsel in 1816. He was appointed Chief Justice of Chester in 1819, and was the last to hold the post: between his death in 1829, and the abolition of the position by the Law Terms Act 1830, the functions were carried out by Thomas Jervis his junior, as Puisne Justice of Chester. In April 1820 he presided over the sedition trial of Sir Charles Wolseley, 7th Baronet and Joseph Harrison, sitting with Samuel Marshall.
