St Leonards-on-Sea (commonly known as St Leonards) is a town and seaside resort in the Borough of Hastings in East Sussex, England. It has been part of the borough since the late 19th century and lies to the west of central Hastings. The original part of the settlement was laid out in the early 19th century as a new town: a place of elegant houses designed for the well-off; it also included a central public garden, a hotel, an archery, assembly rooms and a church. Today's St Leonards has extended well beyond that original design, although the original town still exists within it.
