The Tuscan Committee of National Liberation was an underground Italian resistance organisation during World War II based in Tuscany, Central Italy. An offshoot of the National Liberation Committee (CLN), it was charged with organising resistance and partisan activities throughout Tuscany. It was opposed to the forces of Nazi Germany as well as Nazi Germany's puppet state local regime, the Italian Social Republic, in Tuscany following the German invasion and military occupation of Italy between September 1943 and April 1945. The CTLN became an umbrella organisation for the five main anti-fascist partisan groups operating within Tuscany.
