The proletarian parties were a group of political parties in Japan.
 Several proletarian parties were launched after enactment of the Universal Manhood Suffrage Act in 1925.
 The Farmer-Labour Party had been founded in December 1925, but banned after only two hours of existence.
 Three major proletarian parties emerged during 1926, all closely linked to trade union movements and the divisions between the trade unions were largely replicated in divisions between the political parties.
 The pro-communist trade union centre "Hyōgikai" backed the Labour-Farmer Party.
 The centrist Japan Labour Union League backed the Japan Labour-Farmer Party.
 The moderate "Sodomei" trade union centre backed the Social Democratic Party.
 All these three parties were constructed on the notion of a worker–peasant class alliance.
 Another proletarian party in the fray, the Japan Farmers Party differentiated themselves from this pattern by declaring themselves as a party 'by farmers, for farmers'.
 There were also some local proletarian parties.
