Eurostat is the statistical office of the European Union, in charge of the European Statistical System. It is both a data-collecting institution, but also a statistics standard-setting and harmonization body for EU Member States, European Free Trade Area countries, and EU candidate countries.

Contrary to popular perception, Eurostat is not a separate EU institution, but a Directorate-General of the European Commission. It is located in the Kirchberg Quarter of Luxembourg City, Luxembourg.
