Hauptverwaltung Deutsche Bahn AG, Corporate headquarters in Gallus district, Frankfurt am Main, Germany.

The former Deutsche Bahn AG headquarters is a 67-metre-high-rise designed by architect Stephan Böhm and built by Philipp Holzmann AG between 1991 and 1993. A 17-storey core rises from the middle of five-storey wings, on a 21,037-square-metre site with 45,608 square metres of rental space. The building is listed as a cultural monument under the Hessian monument protection law.

The building was constructed in 1993 as the new headquarters for Deutsche Bundesbahn after the company relocated from its former site near the freight station. This central facility marked a fresh start for rail management following German reunification.

Locals call the building "Alcatraz", after the former prison island, a nickname that stuck during its years as Deutsche Bahn's headquarters. A model near the canteen once showed the planned identical sister building that was never built. The wings are labelled A to C and then I to K, a numbering gap left by that abandoned second phase.

The building is an office complex and cannot be visited inside; it stands in Frankfurt-Gallus, about one kilometre west of the former Bundesbahn site. The Deutsche Bahn moved out after its lease ended in 2020, and the owner now markets the property as RAW for renovation. The entrance area is where the E 04 20 locomotive stood until May 2020.

A historic E 04 20 electric locomotive that entered service in 1934 stood for many years at the building entrance. This locomotive was removed in 2020 and had become a symbol of German railway history.
