Humanist Democratic Centre (French: Centre Démocrate Humaniste, CDH) was a Christian democratic and centrist French-speaking political party in Belgium. The party originated in the split in 1972 of the unitary Christian Social Party (PSC-CVP) which had been the country's governing party for much of the post-war period. It continued to be called the Christian Social Party (French: Parti Social Chrétien, PSC) until 2002 when it was renamed the Humanist Democratic Centre. It was refounded as Les Engagés in 2022.
