Hamburger Hochbahn AG (HHA), founded in 1911, operates the underground system and large parts of the bus system in Hamburg, Germany.
The HHA was founded by Siemens & Halske and AEG as a consortium on 27 May 1911. The first chairman was Albert Ballin.
From 1919 until 1978, the HHA operated a large tram network, and from 5 December 1921 the HHA also operated the first motor buses in Hamburg. After the acquisition of the Straßen-Eisenbahn-Gesellschaft (SEG) in 1919 and the Hamburg-Altonaer-Centralbahngesellschaft AG in 1923, the HHA had a rolling stock of 865 power cars and 930 trailers by 1928.
