Castel /kætel/ (Guernésiais: Lé Casté; French: Sainte-Marie-du-Câtel) is the largest parish in Guernsey in terms of area.

The parish plays host to both Le Viaër Marchi and the North Show which includes the Battle of Flowers annually.

A pre-Christian neolithic menhir dating from 2,500-1,800 BC in the churchyard, carved to represent a female, with breasts and a necklace in relief,[3]: 81  is possibly a fertility symbol.

The church is thought to be built on an ancient fort, hence the name Castel or Câtel,[2] possibly a corruption of the Roman Castellum or castrum.

Those elected (in order of votes received) being Richard Graham, Chris Green, Barry Paint, Mark Dorey and Jonathan Le Tocq.
