Thomas Archer (1668–1743) was an English Baroque architect. His buildings are important as the only ones by an English Baroque architect to show evidence of study of contemporary continental, namely Italian, architecture.

English Baroque is a term used to refer to modes of English architecture that paralleled Baroque architecture in continental Europe between the Great Fire of London (1666) and roughly 1720, when the flamboyant and dramatic qualities of Baroque art were abandoned in favour of the more chaste, rule-based Neo-classical forms espoused by the proponents of Palladianism.
