Southend-on-Sea ( pronunciation (help·info)) is a unitary authority area, town, and seaside resort in Essex, England. The district has Borough status, and comprises the towns of Chalkwell, Eastwood, Leigh-on-Sea, North Shoebury, Prittlewell, Shoeburyness, Southchurch, Thorpe Bay, and Westcliff-on-Sea. The district is situated within the Thames Gateway on the north side of the Thames estuary 40 miles (64 km) east of central London. It is bordered to the north by Rochford and to the west by Castle Point. It is home to the longest leisure pier in the world, The Southend Pier.London Southend Airport is located 2 Miles north of the town Center, and is one of London's 6 Major Airports.

Originally the "south end" of the village of Prittlewell, Southend became a seaside resort during the Georgian era, attracting many tourists in the summer months to its seven miles^{[citation needed]} of beaches and bathing in the sea. Good rail connections and proximity to London mean that much of the economy has been based on tourism, and that Southend has been a dormitory town for city workers ever since. Southend Pier is the world's longest pleasure pier at 1.34 miles (2158m). It has suffered fires and ship collisions, most recently in October 2005, but the basic pier structure has been repaired each time. There has been significant loss of pier-head facilities since the major fire in 1976.
