St Mary (Jèrriais: Sainte Mathie) is one of the twelve parishes of Jersey, Channel Islands.

[4] The parish and its eponymous church derive their name from a medieval monastery, probably destroyed during Viking raids some time between the 8th and 10th centuries.

In 1042 Duke William gave "St Mary of the Burnt Monastery" to the abbey of Cerisy.

La Grève de Lecq is the main bay in the parish and lies on the border with St Ouen.

The parish stands upon coarse-grained granite, 'of St Mary's type', which formed during the lower Palaeozoic period.

The village has extensive traffic calming, including raised junctions, filtered permeability, virtual footpaths and build-outs.

The village won the Chartered Institution of Highways and Transportation award for traffic calming measures introduced in the parish in the 2010s.

In 1858, a new Rector placed new locks on the church doors, removed the bell rope and clapper and took away the ladder to the belfry.

They broke the locks, deposited the doors in the Rectory gardens, awoke the blacksmith to forge a new clapper and one galloped into town to fetch a new rope.

[11] Among the natural attractions of the parish is a feature known as the Devil's Hole[12] (French: Lé Creux du Vis), a blowhole in the cliffs of the coast.

The descent from the car park to the Devil's Hole is a popular tourist attraction, with the walk taking approximately ten minutes.

Lecq originates from the Norse La Wik, which may have meant 'ship-loading creek' or referred to witches, should the bay have been a centre of sorcery.

In the bay Le Moulin de Lecq, an old watermill, was converted into a residence in 1929 and following the Second World War became a pub, while retaining the wheel and remnants of the gears.

[15] St Mary is twinned with Longues-sur-Mer, a commune of the département of Calvados, in the Normandy région of France.
