Great Yarmouth, often known to locals as Yarmouth, is a coastal town in Norfolk, England. It is located at the mouth of the River Yare, 20 miles (32 km) east of Norwich.

It has been a seaside resort since 1760, and is the gateway from the Norfolk Broads to the sea. For hundreds of years it was a major fishing port, depending mainly on herring fishery, but its fishing industry suffered a steep decline and has now all but disappeared. The discovery of oil in the North Sea in the 1960s led to a flourishing oil rig supply industry, and today it services offshore natural gas rigs. More recently, the development of renewable energy sources, especially offshore wind power, has created further opportunities for support services. A wind farm of 30 generators is within sight of the town on the Scroby Sands.

The town has a beach and two piers.

The town itself is on a thin spit sandwiched between the North Sea and River Yare. Its well known features include the historic rows (narrow streets) and the main tourist sector on the seafront. The area is linked to Gorleston, Cobholm and Southtown by Haven Bridge and to the A47, A149 and A12 by the Breydon Bridge.
