A scroll compressor may include a first scroll and a second scroll orbiting relative to the first scroll to form compression chambers, a discharge port provided in the first scroll to discharge refrigerant compressed in the compression chamber, a discharge passage formed through the first discharged through the discharge to an upper side of the frame, and a discharge cover coupled to the first scroll and having a space to accommodate end portions of the discharge port and the discharge passage to guide the refrigerant discharged through the discharge port to the discharge passage. A volume of a discharge space defined in the space by the first scroll may be 4.5 or more, obtained by dividing a volume of the discharge space by a total volume of an initial compression chamber among the compression chambers.
