BACKWORTH, a township, in the parish of Earsdon, union of Tynemouth, E. division of Castle ward, S. division of Northumberland, 7 miles (N. E. by N.) from Newcastle-upon-Tyne; containing 413 inhabitants.

The soil is fertile, and favourable to the growth of wheat; the district abounds in coal, and an extensive colliery is in operation, the produce of which is of a superior quality, and known as "Northumberland Wallsend." The great tithes have been commuted for £107. Sir Charles Grey, Knt., the governor of Barbadoes, was born at Backworth House.
