Donghae Expressway (Korean: 동해 고속도로; Hanja: 東海高速道路; RR: Donghae Gosok Doro; lit. East Coast Expressway) is an expressway in South Korea, connecting Busan to Sokcho. It is numbered 65 and it is planned to eventually extend all the way along the east coast to Haeundae, Busan. Its current length is 62.1 kilometres (38.6 mi), and It is part of the Asia Highway Route 6.

In 1966. the South Korean Government and IBRD investigated about Gangwon Province, and decided to construct a new Industrial road that connected Sokcho, Gangneung and Samcheok. In 1971, the Government decided to construct Gangneung–Mukho (Donghae City) Section. This expressway was the seventh highway opened in South Korea.
