Prittlewell is an inner city area and former civil parish in Southend-on-Sea, in the ceremonial county of Essex, England. Historically, Prittlewell is the original settlement of the city, Southend being the south end of Prittlewell. The village of Prittlewell was originally centered at the joining of three main roads, East Street, West Street, and North Street, which was extended south in the 19th century and renamed Victoria Avenue. The principal administrative buildings in Southend are located along Victoria Avenue, although Prittlewell is served by Prittlewell railway station.
