Ritzaus Bureau A/S, or Ritzau for short, sometimes stylized as /ritzau/, is a Danish news agency founded by Erik Ritzau in 1866. It collaborates with three other Scandinavian news agencies to provide Nordic News, an English-language Scandinavian news service. It is based in Copenhagen and Lars Vesterløkke is editor-in-chief and CEO of the company.

Ritzaus Bureau was founded by Erik Nicolai Ritzau in Copenhagen on 1 February 1866 under the name Nordisk Centralbureau for Telegrammer.^[1] The agency received international news by telegram from Wolffs Bureau (now Deutsche Presse-Agentur, DPA) in Berlin.

Erik Ritzau died in 1904. His son, Lauritz Ritzau, was CEO of the company from 1916 to 1958. The Ritzau family sold Ritzaus Bureau to the Danish newspapers in 1947. In 2007, DR became a co-owner of the agency. The company form was changed from an interessentskab (I/S) to an aktieselskab (A/S) in 2012.

Ritzau collaborates with three other Scandinavian news agencies to provide Nordic News, an English-language Scandinavian news service providing sixty stories daily. Ritzau is a member of the European Gruppe 39 collaboration.

In November 2017, Ritzau acquired Scanpix Denmark from Berlingske Media with effect from 1 January 2018. Scanpix is the leading Danish stock photography agency in Denmark with more than 25 million pictures on stock in its digital and physical archives. It collaborates closely with sister companies in Norway, Sweden and Estonia.^[2]
