St Mary de Haura Church is an Anglican church in the ancient "New Shoreham" area of Shoreham-by-Sea in the district of Adur, one of seven local government districts in the English county of West Sussex. It was founded at the end of the 11th century as a large cruciform church which, due to its original scale, has been described as a collegiate church—a reflection of the port of Shoreham`s importance at the time. The former east end of that building survives to form the present church, and much 12th-century work remains. It functions as Shoreham-by-Sea`s "town church" for major religious and social events, as well as serving its small town-centre parish. English Heritage has listed it at Grade I for its architectural and historical importance.
