The London Underground 1992 Stock is a type of rolling stock used on the Central and Waterloo & City lines of the London Underground. A total of 85 eight-car trains were built for the Central line and 5 four-car trains were built for the Waterloo & City line.

On the Central line, trains entered service in April 1993, with automatic train operation (ATO) and automatic train protection (ATP) effectively allowing the trains to drive themselves. Since 2019, these trains are being refurbished, which includes the replacement of the original motors, installation of CCTV and an overhauled interior.

On the Waterloo & City line, trains entered service as Class 482 in July 1993, before transferring to London Underground in April 1994. These trains were refurbished in the mid 2000s, replacing the Network SouthEast livery with London Underground livery.
