A casing of an oil separator has an inlet port through which blow-by gas flows into the oil separator, and an outlet port through which the blow-by gas flows out of the oil separator. The casing defines a blow-by gas passage that extends to connect the inlet port to the outlet port. A separation mechanism is located in the blow-by gas passage. The separation mechanism traps oil in blow-by gas, thereby separating the oil from the blow-by gas. A drain port is formed in the casing to drain the separated oil. The outlet port is located in one of opposite side portions of the casing. The drain port is located in the other one of the opposite side portions of the casing. The oil separator is capable of reliably suppressing repeated splash of the separated oil.
