The Guangdong–Hainan Ferry, or the Yuehai Ferry (part of the Guangdong–Hainan Railway) is a vehicle and train ferry connecting Hainan Island to Guangdong in mainland China. The ferries run across the Qiongzhou Strait, between Zhanjiang, Guangdong and Haikou, Hainan. A road-rail bridge has been proposed.
