Bayan Muna is a leftist political party in the Philippines.

The motto of the party is "New Politics, the Politics of Change", against "traditional, elitist, pro-imperialist politics". Its platform includes the advocation of a government that progressively supports the working class, with meaningful representation of all democratic sectors in the Philippines. Bayan Muna was the second most popular party-list party in the 2007 Philippine elections.
