Trafikselskabet Movia is the public transport agency that is responsible for buses and certain local railways in Copenhagen and the part of Denmark east of the Great Belt, covering the regions Sjælland and Hovedstaden, except for Bornholm, which is a 100% owner of BAT, formerly, before 1 January 2003, transit agency Bornholms Amts Trafikselskab.

It has an integrated fare system in collaboration with the Copenhagen metro and DSB, which means that the same tickets are valid on all buses and trains.

Movia was created on January 1, 2007, as part of the 2007 municipal reform.

A new seamless fare system which replaces most paper tickets by contactless smartcard has been implemented.

[5] Movia has eleven night bus lines which operate between the hours of 01:00 and 05:00.
