The Workers' Party of Belgium (French: Parti du Travail de Belgique, PTB; Dutch: Partij van de Arbeid van België, PVDA; lit. 'Labour Party of Belgium') is a Marxist and socialist political party in Belgium. It is the only Belgian party represented in parliament that is a fully national party, representing both Flanders and Wallonia. Having historically been a small party, the PTB-PVDA has gained momentum since the 2010s, continuously scoring better at the elections, particularly in Wallonia and working-class communities in Brussels.
