The Reformist Movement[2][3] (French: Mouvement réformateur, pronounced [muvmɑ̃ ʁefɔʁmatœʁ], MR) is a liberal[4][5][6] French-speaking political party in Belgium, which includes social-liberal[7][8][9] and conservative-liberal factions.

Just a few days after the elections, the MR announced it would work closely with Les Engagés to quickly form governments in the Walloon Region and the French community.

The Liberal Reformist Party (PRL) and the Francophone Democratic Federalists (FDF) started the alliance in 1993, and were joined in 1998 by the Citizens' Movement for Change (MCC).

They did not agree with the manner in which president Charles Michel defended the rights of the French-speaking people in the agreement concerning the splitting of the Brussels-Halle-Vilvoorde district, during the 2010–11 Belgian government formation.

[20] On its current platform, the party advocates higher revenues through lower taxes; time-limited unemployment benefits; life extension of the most recent nuclear reactors; greater investment in police, justice and defense; less government and state neutrality.

[24] In the European Parliament, Mouvement Réformateur sits in the Renew Europe group with three MEPs: Sophie Wilmès, Olivier Chastel and Benoit Cassart.
