Grosnez Castle is a ruined 14th-century castle in Saint Ouen, situated in Grosnez in the north-west corner of the island of Jersey in the Channel Islands. Philippe de Carteret held it against the French when they held half of Jersey between 1461 and 1467, but it has been a ruin since the mid-16th century.
Grosnez Castle is open to the public. There is small automated signal station at the rear of the castle that affords scenic views.
