Alliance of Liberals and Democrats for Europe group

The Group of the Alliance of Liberals and Democrats for Europe (ALDE Group) was the liberal–centrist political group of the European Parliament from 2004 until 2019 when it merged into Renew Europe.

ALDE was made up of MEPs from two European political parties, the Alliance of Liberals and Democrats for Europe Party and the European Democratic Party, which collectively form the Alliance of Liberals and Democrats for Europe.

The ALDE Group traced its unofficial origin back to September 1952 and the first meeting of the Parliament's predecessor, the Common Assembly of the European Coal and Steel Community. Founded as an explicitly liberal group, it expanded its remit to cover the different traditions of each new Member State as they acceded to the Union, progressively changing its name in the process. Its immediate predecessor was the European Liberal Democrat and Reform Party Group (ELDR).

The ALDE Group was the fourth-largest group in the Eighth European Parliament term, and previously participated in an informal coalition with the EPP during the Sixth Parliament (2004–2009). The pro-European platform of ALDE was in support of free market economics and pushed for European integration and the European single market.

On 12 June 2019, it was announced that the successor group in alliance with La République En Marche! would be named Renew Europe.
