EUobserver is a European online newspaper, launched in 2000 by the Brussels-based organisation EUobserver.com ASBL.

The newspaper provides both daily reports and in-depth coverage on international affairs related to the European Union (EU).

[1] It is regarded as one of the first English language media outlets dedicated to the reporting of EU affairs,[2] since joined by The Brussels Times, EURACTIV and Politico Europe.

[8] The newspaper claims both financial independence from EU institutions and a daily circulation of 60,000.

[9][10] In a 2008 poll of 100 Brussels-based journalists by APCO, one third claimed to use the publication as their source for EU news, making it, at the time, the "second most influential" media outlet reporting on EU affairs behind the Financial Times.
