A scroll compressor includes an orbiting scroll that is coupled to a rotating shaft in a casing and includes an orbiting end plate portion coupled to the rotating shaft and an orbiting wrap that has a spiral shape protruding from one surface of the orbiting end plate portion, a fixed scroll including a fixed wrap that is engaged with the orbiting wrap defines a compression chamber with the orbiting wrap therebetween, and a main frame that rotatably supports the orbiting scroll and defines a back pressure chamber with the orbiting scroll. The fixed scroll defines a fixed back pressure hole having a first end configured to communicate with the first back pressure chamber and a second end is located between outer and inner circumferences of the orbiting wrap. The orbiting wrap is configured to cover at least a portion of the fixed back pressure hole during the orbital motion.
