Saint Helier Harbour is the main harbour on the Channel Island of Jersey. It is on the south coast of the island, occupying most of the coast of the main town of St Helier. It is operated by Ports of Jersey, a company wholly owned by the Government of Jersey.

Before 1700 St Helier had no decent harbour although a map of 1545 does show two stone piers in the area under Le Mont de la Ville, near where South Pier is today. The modern harbour dates back to the construction of the stone fronted quay at La Folie in the early 1700s.

Etymology: Saint Helier Harbour is named after Helier, a 6th-century ascetic hermit from Belgium. The traditional date of his martyrdom is AD 555. His feast day, marked by an annual municipal and ecumenical pilgrimage to the Hermitage, is on 16 July.

History: The harbour was constructed in the early 19th century. Previously, ships coming into the town had only a small jetty at the site now called the English Harbour and the French Harbour. The Chamber of Commerce urged the States Assembly to build a new harbour, but they refused, so the Chamber took it into their own hands and paid to upgrade the harbour in 1790. A new breakwater was constructed to shelter the jetty and harbours. In 1814, the merchants constructed the roads now known as Commercial Buildings and Le Quai des Marchands to connect the harbours to the town and in 1832 construction was finished on the Esplanade and its sea wall. A rapid expansion in shipping led the States of Jersey in 1837 to order the construction of two new piers: the Victoria and Albert Piers.

The Old harbour: English Harbour and French Harbour have berths for over 500 motorboats and sailing yachts which dry out on the mud at low tide.

Main harbour: The main harbour provides deep water berths for commercial vessels alongside the Victoria Quay and New North Quay. On Victoria Quay you will find fish wholesalers such as, Fresh Fish Company and Aquamar Fisheries. Albert Pier has now been re-developed from a ferry terminal to new berths for large vessels and yachts.

Elizabeth harbour: The Elizabeth Harbour consists of a ferry terminal, two roll-on/roll-off ferry berths and a trailer park for shipping containers. These are used by high-speed craft to Poole, Guernsey and Saint-Malo, traditional ferries to Saint-Malo, Guernsey and Portsmouth and foot passenger ferries to Granville, Barneville-Carteret and Sark.

Marinas: There are three marinas — the La Collette Yacht Basin, the Saint Helier Marina (built in 1980) and the Elizabeth Marina. The La Collette Yacht Basin is the only one of these to provide non-tidal, 24-hour access to the sea and is home to Jersey’s commercial fishing fleet.
