Southend Pier is a major landmark in Southend-on-Sea, Essex, United Kingdom. Extending 2.16 kilometers into the Thames Estuary, it is the longest pleasure pier in the world.

The Southend Pier Railway is a 914 mm narrow gauge railway in the English city of Southend-on-Sea, Essex. It runs for 2.01 km along the 2.16 km length of Southend Pier, providing public passenger transport from the shore to the pier head.

The line is owned and operated by Southend-on-Sea City Council, and operates every day the pier is open. The normal service uses a single train and runs every half-hour. At peak times a two-train service is operated, providing a 15-minute interval service. Trains operate between stations known as Shore and Pier Head with no intermediate stops.

The train service is provided by one diesel train and one battery-electric train. The diesel train consists of a diesel-hydraulic locomotive at the southern end, five trailer coaches, and, at the northern end, a driver control unit with passenger space and is named Sir William Heygate. A second former diesel train, Sir John Betjeman, has been decommissioned, the locomotive parked at the pier end station, and the carriage bodies removed from their chassis and reused as waiting shelters at various places in the station and around the pier. The first battery-electric train was named Sir David.

A twin-track island platform is provided at each terminus, and there is a passing loop in the mid-pier, but otherwise, the line is single-tracked. The pier head terminus is in the open air, but the shore terminus is enclosed, and also provides rail access to a workshop for maintaining the trains. The Southend Pier Museum is situated below the shore station in the original workshops.
