Breydon Water is a 514.4-hectare (1,271-acre) biological Site of Special Scientific Interest at Great Yarmouth, Norfolk.^[1][3] It is a Local Nature Reserve,^[4] a Ramsar site^[5] and a Special Protection Area.^[6] It is part of the Berney Marshes and Breydon Water nature reserve, which is managed by the Royal Society for the Protection of Birds (RSPB).^[7]

It is a large stretch of sheltered estuary. It is at the gateway to The Broads river system on the eastern edge of Halvergate Marshes. It is the UK's largest protected wetland. It is 5 km (3 mi) long and more than 1.5 km (0.9 mi) wide in places.

Breydon Water is overlooked at the southern end by the remains of the Roman Saxon Shore fort at Burgh Castle. Centuries ago, Breydon Water would have been one large estuary facing the sea. At the western end the water may be considered to start at the confluence of the River Yare and River Waveney; smaller sources including The Fleet flow in from the surrounding marshland. Safe passage for boats is indicated by red and green marker posts. Unlike most of the navigable waterways in the Norfolk Broads, Breydon Water is not subject to a speed limit.

At the east end of Breydon Water the river returns to a narrow channel, passing under Breydon Bridge after which it is joined by the River Bure then under Haven Bridge from where it is 4.4 km (2.7 mi) through the harbour into the North Sea.
