The Norfolk wherry is a type of sailing boat used on The Broads in Norfolk and Suffolk, England. Three main types were developed over its life, all featuring the distinctive gaff rig with a single, high-peaked sail and the mast stepped well forward.

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.
