Jerusalem–Yitzhak Navon Railway Station (originally named Jerusalem–HaUma railway station) is an Israel Railways passenger terminal in Jerusalem, located at 6 Shazar Avenue.
The station was constructed in 2007 and was completed in 2018 at a cost of about NIS 500 million (appx. $140 million). It is located across from Binyanei HaUma and constitutes part of a major public transportation hub, being situated adjacent to the Jerusalem Central Bus Station as well as next to a station serving current and future lines of the Jerusalem Light Rail.
The station is the eastern terminus of the Tel Aviv–Jerusalem railway. It is the world's deepest heavy-rail passenger station, the fourth deepest underground station in the world, and the deepest underground station outside the former Soviet Union, with its platforms extending down to 80 metres (260 ft) below street level.
Due to the constraints of building the Tel Aviv–Jerusalem railway in a grade suitable for carrying passengers, the station platforms had to be built 80 metres below street level, at the end of a tunnel leading to the railroad bridge over Emeq HaArazim.
The underground portion of the station is built as a pylon tri-vault. The side vaults each host one of the two island platforms, and are linked by three pairs of overpasses to the central vault. The length of the platforms is 300 metres (980 ft), and the temperature inside remains consistent year-round.
