List of European Commissioners by nationality

A European Commissioner is a member of the European Commission. Each Commissioner within the college holds a specific portfolio and are led by the President of the European Commission. In simple terms they are the equivalent of national ministers. Each European Union member state has the right to a single commissioner (before the Barroso I Commission in November 2004, the five largest states—France, Germany, Italy, Spain and the United Kingdom—were granted two) and appoints them in consultation with the President.

The accession of Romania and Bulgaria in 2007 raised the number of commissioners from 25 to 27, and after the accession of Croatia in 2013 the number of commissioners raised to 28. The United Kingdom left the EU on 31 January 2020, and did not nominate a commissioner when the Juncker Commission ended on 1 December 2019.

Below is a list of all past and present European Commissioners according to the member-state they were nominated by, including the Presidents of the European Coal and Steel Community and European Atomic Energy Community. The colours indicate their political background (blue for conservative or centre-right, mainly the European People's Party; red for left-wing or social democrats, mainly the Party of European Socialists; yellow for centrist or liberals, mainly the Alliance of Liberals and Democrats for Europe Party; green for green politicians, mainly the European Green Party; and their pan-European predecessors).
