Sir Henry Gwillim (c. 1760 - 22 September 1837, Staplefield, Sussex) was a British judge who served for some time in the Supreme Court at Madras as a puisne judge. He came to be called the "irascible Welshman" and was recalled after a case involving the Governor Lord William Bentinck. Gwillim published a few books and compilations on laws including A New Abridgment of the Law (1860) running into several volumes and editions and a four-volume A Collection of Acts and Records of Parliament, with Reports of Cases argued and determined in the courts of Law and Equity respecting Tithes (1801).
