The parish of Grouville shares, with the neighbouring parish of Saint Martin, a dedication to Saint Martin of Tours. The ecclesiastical parish and parish church are dedicated to "Saint Martin de Grouville" to distinguish them from the parish of Saint Martin (historically 'Saint Martin le Vieux'). The Church of St Peter la Rocque was built in the 19th century.
The name 'Grouville' may derive from:
- the small community established in what is now the parish by St Gerou (also known as Gervold or Geraldius), an ecclesiastical troubleshooter in the employ of Charlemagne in the 9th century AD;
- 'Gros Villa' (great farm)
- Geirr, the Viking leader after whom the Island may be named.
The Royal Bay of Grouville gained its royal epithet when it impressed Queen Victoria during her visit in 1846. The bay is popular with tourists for its broad sandy beach and shallow, warm water. It is also the main oyster producing area of Jersey, and was also formerly noted for the gathering of vraic (seaweed) for spreading on fields over the winter before planting potatoes the following year. Parishioners also used to burn vraic, giving rise to the traditional nickname of les Enfuntchis (the smoky ones, or the dim ones, in Jèrriais) shared by the Grouvillais and their neighbours in Saint Clement.Inland, the parish is also home to Jersey's most noted archaeological site at La Hougue Bie, now a museum run by the Jersey Heritage Trust. A prehistoric artificial mound covers a passage grave aligned for the equinox. A mediaeval chapel, Notre Dame de la Clarté, built on the Neolithic mound, was converted in the 18th century to a folly-like residence, the Prince's Tower (demolished in the 1920s). Second World War, the occupying German forces constructed bunkers in and alongside the ancient mound, now also transformed for museum interpretation.
La Rocque was the site of the landing of the French forces on 6 January 1781. The skirmish at La Platte Rocque was ancillary to the Battle of Jersey.
The Royal Jersey Golf Club, Gorey Village, and Queen's Valley (now flooded to form a reservoir) are situated in the parish.
Grouville is divided for administrative purposes into vingtaines as follows:
