Charles Rann Kennedy (born 1808; died December 17, 1867 in Birmingham) was an English lawyer.

The brother of Benjamin Hall Kennedy, he was educated at Shrewsbury School and Trinity College, Cambridge, where he graduated as senior classic (1831). He then became a barrister. From 1849-1856 he was professor of law at Queen's College, Birmingham. As adviser to Mrs Swinfen, the plaintiff in the celebrated will case Swinfen v. Swinfen (1856), he brought an action for remuneration for professional services, but the verdict given in his favour at Warwick assizes was set aside by the court of Common Pleas, on the ground that a barrister could not sue for the recovery of his fees. The excellence of Kennedy's scholarship is abundantly proved by his translation of the orations of Demosthenes (1852-1863, in Bohn's Classical Library), and his blank verse translation of the works of Virgil (1861). He was also the author of New Rules for Pleading (2nd ed., 1841) and A Treatise on Annuities (1846).

His grandson, also named Charles Rann Kennedy (1871 - 1950), was a playwright and actor who married actress Edith Wynne Matthison.
