DB Regio AG (German pronunciation: [deːbeː ˈʁeɡi̯o]) is a subsidiary of Deutsche Bahn which operates regional and commuter train services in Germany.

The articles of association for DB Regio GmbH were concluded on 12 February 1998, and the company was entered in the commercial register on 6 April 1998.

Its sole purpose was the "preparation of the outsourcing of the local passenger transport division of Deutsche Bahn Aktiengesellschaft to a newly founded stock corporation in legal, economic and organizational terms".

[5] By resolution of 27 April 1999 the company was renamed Deutsche Bahn Erste Philippe Dressel mbH, the object of which was the "administration of its own assets and any activities that are conducive to the aforementioned purpose".

[8] In 2007, DB Regio achieved 70% of its turnover from payments made by the federal states for the provision of local public transport, 29% from ticket sales and 1% from other income.

After winning the tender, around 180 employees from DB Regio NRW should switch to the subsidiary that is not bound by the collective agreement of the group and receive around a fifth less wages there, according to a press report.

[10] From 2004 to the end of 2010, the DB Stadtverkehr subsidiary founded for this purpose was responsible for operating bus and city traffic.

[15] In the late summer of 2016, the company announced that it would take part in the upcoming award procedures with smaller, more flexible units.

[17] Due to the COVID-19 pandemic in Germany, capacity utilization fell to around 70 percent of the previous level in 2020, according to Berthold Huber, Deutsche Bahn board member responsible for passenger transport.

The headquarters of DB Regio in Frankfurt is responsible for the business development and focuses on the framework and service functions for the regional units in the conclusion of transport contracts and tenders.

In addition, there are five urban commuter trains (S-Bahn), which are run directly from the headquarters, as well as the independent regio networks (RegioNetz).

This is a permanent special offer and entitles up to five people to travel on all DB Regio local trains throughout Germany on Saturdays or Sundays.
