Regency Square is a large early 19th-century residential development on the seafront in Brighton, part of the British city of Brighton and Hove. Conceived by speculative developer Joshua Hanson as Brighton underwent its rapid transformation into a fashionable resort, the three-sided "set piece" of 69 houses and associated structures was built between 1818 and 1832. Most of the houses overlooking the central garden were complete by 1824. The site was previously known, briefly and unofficially, as Belle Vue Field.
