Mukho () is a harbor in Donghae City, Gangwon Province, South Korea. It is located on the shore of the Sea of Japan . In the past it played an important role in the shipping of iron ore and coal; much of this role has been taken over by Donghae Harbor in recent years. Mukho is an important harbor of refuge and home to a large number of fishing vessels. A passenger ferry operates from the port to Ulleung Island. The harbor is connected to land-based transportation by two stations on the Yeongdong Line and an interchange on the Donghae Expressway. The ship Mangyongbong 92 carrying a 140 person delegation for the 2018 Winter Olympics from North Korea berthed at this harbor, as protesters opposing North Korea subsequently gathered singing Aegukga. The harbor first opened in 10.14.1937.
