Rockingham Bay is a bay in Far North Queensland, Australia.
The bay opens onto the Coral Sea, part of the South Pacific Ocean. Adjacent to the bay is the Edmund Kennedy National Park, south of which is the town of Cardwell. Goold Island is a small island in the bay, and south of this is Hinchinbrook Island, a larger island.
The bay was significant in the exploration of the Cape York peninsula by Edmund Kennedy in 1848. He was landed here with a group of twelve men, to begin the journey north. On the way, Kennedy left eight members of the expedition at Weymouth Bay, intending to pick them up later on the return by sea. However Kennedy and all but one member died later during the journey; all but two of the eight members left at Weymouth Bay died before they were relieved.
