Newcastle East is an inner city suburb of Newcastle, New South Wales, Australia, located immediately east of Newcastle's central business district at the mouth of the Hunter River. The Awabakal and Worimi peoples are acknowledged by City of Newcastle as the descendants of the traditional custodians of the land situated within the Newcastle local government area, including wetlands, rivers creeks and coastal environments. It is known that their heritage and cultural ties to Newcastle date back tens of thousands of years. The suburb includes Fort Scratchley, Newcastle Ocean Baths and Newcastle Beach. Formerly a site of heavy industry and railway yards, the suburb now contains the large Foreshore Park, and historic terraced housing.

Newcastle East is home to two of Newcastle's beaches, Nobbys Beach and Newcastle Beach, both of which have surf lifesaving clubs and are patrolled by lifesavers. In June 2007, the bulk carrier Pasha Bulker grounded itself off Nobbys Beach in a storm. Between Newcastle and Nobbys beaches lie the Newcastle Ocean Baths.

Fort Scratchley is a fort atop a knoll overlooking Nobbys Beach. It was designed by Lt. Col. Peter Scratchley and built between 1881 and 1886. While its original purpose was to protect the colony against a feared Russian invasion, its most prominent role came during World War II when the guns at the fort fired upon a Japanese submarine which shelled the city in 1942. The military role of the fort came to an end in 1972 and it now houses the Newcastle Region Maritime and Military Museum. Damage from the Japanese Navy attack during World War II can still be seen on the front of some of the buildings in East End. Today Fort Scratchley is a visitor attraction with views of the city and coastline, displays of military artefacts, and tunnel tours. Fort Scratchley also has a library of military books operated by the Fort Scratchley Historical Society.
