Volk's Electric Railway (VER) is a narrow gauge heritage railway that runs along a length of the seafront of the English seaside resort of Brighton. It was built by Magnus Volk, the first section being completed in August 1883, and is the oldest still operating electric railway in the world. 

It was not the first electric railway to be built, but was preceded by Werner von Siemens' 1879 demonstration line in Berlin and by the Gross-Lichterfelde Tramway of 1881, although neither of these now remain in operation.

Operated as an historical seafront tourist attraction, the railway does not usually run during the winter months, and its service is also liable to occasional suspension due to severe weather or maintenance issues.

Today the line runs between terminal stations at Aquarium (a short distance from the Palace Pier) and Black Rock (at Black Rock, not far from Brighton Marina), with an intermediate station and depot at Halfway.

The line has a 2 ft 8 1⁄2 in (825 mm) narrow gauge, is electrified at 110 V DC using a third rail, and is one mile (1.6 km) long.
