Birmingham New Street, also known as New Street station, is the largest and busiest of the three main railway stations in Birmingham city centre, England, and a central hub of the British railway system. It is a major destination for Avanti West Coast services from London Euston, Glasgow Central and Edinburgh Waverley via the West Coast Main Line, the CrossCountry network, and for local and suburban services within the West Midlands; this includes those on the Cross-City Line between Lichfield Trent Valley, Redditch and Bromsgrove, and the Chase Line to Walsall and Rugeley Trent Valley. The three-letter station code is BHM.

The station is named after New Street, which runs parallel to the station, although the station has never had a direct entrance except via the Grand Central shopping centre. Historically, the main entrance to the station was on Stephenson Street, just off New Street. As of 2022, the station has entrances on Stephenson Street, Smallbrook Queensway, Hill Street and Navigation Street.

New Street is the fifth busiest railway station in the UK and the busiest outside London, with 46.5 million passenger entries and exits between April 2019 and March 2020. It is also the busiest interchange station outside London, with just over 7 million passengers changing trains at the station annually. In 2018, New Street had a passenger satisfaction rating of 92%, the third highest in the UK.

The original New Street station opened in 1854. At the time of its construction, the station had the largest single-span arched roof in the world. In the 1960s, the station was completely rebuilt. An enclosed station, with buildings over most of its span and passenger numbers more than twice those it was designed for, the replacement was not popular with its users. A £550m redevelopment of the station named Gateway Plus opened in September 2015; it includes a new concourse, a new exterior facade and a new entrance on Stephenson Street.
