Organisation of Toilers' Fedayan of Afghanistan (Persian: سازمان فداییان زحمتکشان افغانستان, abbreviated سفزا, transliterated Sazman-e-Fedayan-e-Zahmatkashan Afghanistan, 'SAFZA') was a leftwing group in Afghanistan. It was formed after a section of youth cadres had broken away from the Settam-e-Milli group. Like the Settam-e-Milli grouping and its later incarnation SAZA, SAFZA was part of the 'ethnic left' based amongst the peoples of North and North-Eastern Afghanistan, opposed to Pashto political dominance.
The founders of SAFZA had broken away from the Settam-e-Milli group, arguing that the movement should to uphold continue the line of armed struggle, also after the Saur Revolution. It formed a militia force operating in the Northern and North-Eastern parts of the country.
The main leader of SAFZA was Maulawi Bahauddin Ba'es, who described himself as an Islamic socialist.
After a failed uprising in Badakhshan in August 1979, Ba'es was captured and killed in captivity. SAFZA was officially disbanded in 1984, and the remaining leaders joined the then governing People's Democratic Party of Afghanistan. However, SAFZA militias continued to operate. The remaining SAFZA militia elements in Darvaz district, Badakhshan were demobilised through the United Nations Disarmament, Demobilization and Reintegration programme in 2004.
