Berliner Tageszeitung German Newspaper (styled BERLINER TAGESZEITUNG and also known colloquially as BTZ) is a German daily online newspaper. It is liberal conservative in its editorial approach, which is determined not by the chief editor, but by the licensing society publishing this newspaper under the license issued on contractual basis for a fixed term. The licenser, BASILISK Inc., is located in the United States and has a subsidiary in Russia. The newspaper covers the following topics: politics, economics, science, sport, culture, media, Internet and entertainment. Since 2007, the newspaper has revived the name of the former Berliner Tageblatt as an alternate trademark.

Berliner Tageszeitung employs editors in such fields as politics, economy, sports, entertainment, culture, travel, media, science and the Internet. The articles it publishes include both reports written by the editors, reports from various news agencies, and purchased texts. Simon Rowles and Raiko Opitz act as Editor-in-chief.

The newspaper has been published online seven days a week since 1 December 2004. A paywall is planned to be introduced at the end of 2014.

Since March 30, 2004, Berliner Tageszeitung has also produced a daily podcast.

Since July 31, 2007, the Berliner Tageszeitung has used the name of the defunct Berliner Tageblatt (published 1872–1939) as an alternate trademark. On that date the owner of the Berliner Tageszeitung trademark, Rosemarie Opitz, registered the use of the Berliner Tageblatt title with the Deutsches Patent- und Markenamt (German Patent and Trade Mark Office). Both names are legally registered.

Beginning April 1, 2014, the Berliner Tageblatt is a separate online publication from the Berliner Tageszeitung.

The publisher of the Berliner Zeitung, Berliner Verlag GmbH, considered the similarity of names between Berliner Zeitung and Berliner Tageszeitung a hindrance to the activities of their newspaper, and therefore asked the Berliner Tageszeitung to end use of the name. On 19 December 2007 the Landgericht Berlin found in favour of the claim and issued a prohibiting court order; this was subsequently reversed on 22 January 2008 by resolution of the Regional Court of Berlin.Berliner Verlag appealed the decision to the Supreme Court of Berlin (Kammergericht), but withdrew the appeal in a letter dated 7 August 2008. In a statement dated 22 July 2008 the Supreme Court of Berlin further explained that the appeal was denied pursuant to paragraph 2 sentence 1 of § 522 of the Code of Civil Procedure on the ground that it is unreasonable. On this basis the resolution of the Regional Court of Berlin of 22 January 2008 entered into force with urgency for the subsequent issuance of a court order providing the claims of the party.
