Sir Henry Charles Englefield, 7th Baronet FRS FRSE FSA FLS (1752 – 21 March 1822) was an English antiquary and astronomer.
Owing, however, to his being a Catholic, objection was taken to his re-election; another factor was his opposition to the 1797 election to the Society of the architect James Wyatt.
Under his direction the society produced between 1797 and 1813 a series of engravings of English cathedrals, to which he contributed dissertations on Durham, Gloucester, and Exeter.
Besides his antiquarian studies, which he published in contributions to Archaeologia, he carried on research in chemistry, mathematics, astronomy, and geology.
In its conflict with the Vicars Apostolic he contributed a pamphlet in answer to Samuel Horsley, an Anglican prelate, later pro-Catholic, before the Catholic Relief Bill of 1791.
