Alnwick is a market town in Northumberland, England, of which it is the traditional county town. The population at the 2011 Census was 8,116.
The town is on the south bank of the River Aln, 32 miles (51 km) south of Berwick-upon-Tweed and the Scottish border, 5 miles (8 km) inland from the North Sea at Alnmouth and 34 miles (55 km) north of Newcastle upon Tyne.
The town dates to about AD 600 and thrived as an agricultural centre. Alnwick Castle was the home of the most powerful medieval northern baronial family, the Earls of Northumberland. It was a staging post on the Great North Road between Edinburgh and London. The town centre has changed relatively little, but the town has seen some growth, with several housing estates covering what had been pasture and new factory and trading estate developments along the roads to the south.
