A scroll compressor is provided that may include a casing; a drive motor; a fixed scroll that forms a compression space by being coupled to the orbiting scroll; and a discharge cover provided at an inner space of the casing, the discharge cover having a space that communicates with the compression space and separated from the inner space of the casing, and having one or more discharge hole on a side surface thereof, the one or more discharge hole providing communication between an inside and an outside of the space. With such a configuration, vibration noise of the scroll compressor may be more reduced in comparison with a case in which an oil separator is provided outside of the casing. Further, as an area of the one or more discharge hole and a volume of the space are optimized, efficiency of the scroll compressor may be enhanced.
