Thomas Baldwin (c.1750 – 7 March 1820) was an English architect in the city of Bath, who was responsible for designing some of Bath's principal Georgian buildings. In 1775, he was appointed as the official Bath City Architect. In this role he designed Guildhall, Argyle Street, Laura Place, Great Pulteney Street and many others. In 1793, he was dismissed for financial irregularities, and as a result he was forced into bankruptcy and his reputation was ruined. Jane Root, biographer of Baldwin, writes; "he had a history not merely of imprudence, but of deliberate dishonesty".
