Aylsham (/ˈeɪlʃəm/ or /ˈeɪlsəm/) is a historic market town and civil parish on the River Bure in north Norfolk, England, nearly 9 mi (14 km) north of Norwich. The river rises near Melton Constable, 11 miles (18 km) upstream from Aylsham and continues to Great Yarmouth and the North Sea, although it was only made navigable after 1779, allowing grain, coal and timber to be brought up river.
The town is close to large estates and grand country houses at Blickling, Felbrigg, Mannington and Wolterton, which are important tourist attractions.
The civil parish has an area of 4,329 acres (17.52 km2) and in the 2001 census had a population of 5,504 increasing to a population of 6,016 at the 2011 census. For the purposes of local government, the parish falls within the district of Broadland.
