St. Aubin (Jèrriais: Saint Aubîn) is a town and port in La Vingtaine du Coin, St. Brelade in Jersey, the largest of the Channel Islands. It is located on the western end of St. Aubin's Bay, on the south coast of the island, opening out into the Gulf of Saint-Malo.
St. Aubin was originally a fishing village[1] and the historic economic centre of the island. The Jersey Railway historically terminated in the town, at what is now the parish hall.[2] The Railway Walk, a trail following the route of the former Jersey Railway to La Corbière, starts from St Aubin.[3]
The town is the civil administrative centre for the parish of St. Brelade; however, ecclesiastically, the parish church is located in St. Brelade's Bay. It retains a much more historic character than St. Helier, whose architecture has changed as the centre of Jersey's finance industry.
