Sir John Thomas Briggs (4 June 1781 – 3 February 1865) was an English civil servant who was accountant-general of the Royal Navy. He came from an old Norfolk family, a direct descendant of Dr. William Briggs, and, in a collateral line related to Professor Henry Briggs, was born in London on 4 June 1781. He died at his home, 4 Royal Crescent, Brighton on 3 February 1865. His wife, to whom he was married in 1807, survived him several years, and died at the age of ninety, on 24 December 1873.
