Belfast Harbour is a major maritime hub in Belfast, Northern Ireland, handling 67% of Northern Ireland's seaborne trade and about 25% of the maritime trade of the entire island of Ireland. It is a vital gateway for raw materials, exports and consumer goods, and is also Northern Ireland's leading logistics and distribution hub. The Belfast Harbour Estate is home to many well-known Northern Ireland businesses such as George Best Belfast City Airport, Harland and Wolff, Bombardier Aerospace, Odyssey, the Catalyst Inc, Titanic Quarter and Titanic Belfast. Over 700 firms employing 23,000 people are located within the estate. Belfast is only one of two ports on the island of Ireland to handle a full range of cargoes, from freight vehicles to containers, dry, break and liquid bulk, as well as passenger services and cruise calls. Belfast Harbour handled 23 million tonnes of cargo during 2015, similar to its throughput for 2014. The tonnages suggest a varying performance between sectors in the wider Northern Ireland economy. BBC One Northern Ireland began a three-part documentary (4 parts when broadcast in 2022) on Belfast Harbour entitled Belfast Harbour: Cruises, Cranes and Cargo on 14 April 2020 examining the role of the Port of Belfast in Northern Ireland's economy.

This small and most obscure port was the nucleus of the great docks and harbour of modern days." Records show that by 1663 there were 29 vessels owned in Belfast with a total tonnage of 1,100 tonnes. Trade continued to expand throughout the century, to the extent that the original quay was enlarged, to accommodate the increasing number of ships. By the early 18th century Belfast had replaced Carrickfergus as the most important port in Ulster and additional accommodation was necessary. A number of privately owned wharves were subsequently constructed on reclaimed land. Throughout the century trade continued to expand as Belfast assumed
