Trinity Broads is a 316.8-hectare (783-acre) biological Site of Special Scientific Interest north of Great Yarmouth in Norfolk. They are in The Broads Special Area of Conservation. They are also part of the Broads National Park in Norfolk, England, comprising 5 broads in total. The three largest are Rollesby Broad, Ormesby Broad and Filby Broad, and there are two much smaller broads named Lily Broad and Ormesby Little Broad. They are managed by the Broads Authority.

The Broads is a network of mostly navigable rivers and lakes in the English counties of Norfolk and Suffolk. Although the terms "Norfolk Broads" and "Suffolk Broads" are correctly used to identify specific areas within the two counties respectively, the whole area is frequently referred to as the Norfolk Broads.
