Myuna Bay is a suburb of the City of Lake Macquarie in New South Wales, Australia, and is located west of Lake Macquarie near Wangi Wangi.
Myuna Bay is largely undeveloped. It has a rest area on Wangi Road, dating back to when Wangi Road was the main road along the western shoreline of Lake Macquarie before the completion of the Sydney-Newcastle Freeway.
Myuna Bay is home to the government of New South Wales Myuna Bay Sport and Recreation Centre.
