The Patriotic Front (PF) is a social democratic political party in Zambia. The party was formed by Michael Sata as a breakaway party of the Movement for Multiparty Democracy (MMD) in 2001 after the President Frederick Chiluba nominated Levy Mwanawasa as its presidential candidate for 2001 elections. The party's main base of support are usually the youth and poor people in urban centres (although this support wavered starting in 2021), as well as members of the Bemba people in Copperbelt Province and Lusaka Province.
