William Mathews (born 23 March 1793 at Crondall, Hampshire; died 20 August 1858 at Woodbridge, Suffolk) was an English professional cricketer who played first-class cricket from 1821 to 1830. He was mainly associated with Surrey and made 31 known appearances in first-class matches.
Mathews took part in the Gentlemen v Players matches between 1824 and 1830, usually representing the Players, but in 1825, he was a given man for the Gentlemen. He played for All-England in the 1827 roundarm trial matches and was one of the signatories to the petition after the second game that called upon the authorities to ban roundarm.
