Thomas Dudley Fosbroke (sometime Fosbrooke) FSA (27 May 1770 – 1 January 1842) was an English clergyman and antiquary.

He wrote British Monachism (2 volumes, 1802), an examination of English monastic life, as well as the Encyclopaedia of Antiquities (1824) and its sequel, Foreign Topography (1828).

He was an important historian of Gloucester, writing two volumes on the history of that city.

He matriculated at Pembroke College, Oxford in 1785, graduating BA in 1789 and MA in 1792.

He then removed to Walford in Herefordshire, and remained there the rest of his life, as curate until 1830, and afterwards as vicar.
