Woy Woy Bay is a suburb located in the Central Coast region of New South Wales, Australia, as part of the local government area. Most of the suburb's area belongs to the Brisbane Water National Park, although a small community on Woy Woy Bay (part of Brisbane Water) containing a community hall, public reserve and wharf is also located within the suburb. Woy Woy Bay is commonly used by boaters on the weekend because of the open expanses of the bay. The main thoroughfare is Taylor Street.
