Brighton Beach, Coastal beach in South Georgia and the South Sandwich Islands, United Kingdom.

Brighton Beach is a stretch of shore on the west side of Possession Bay in northern South Georgia, running from Adventure Point south to Zero Point, which sits at the north side of Assistance Bay. It lies at the head of the bay, where Inner Reef extends from Adventure Point to Brown Point, and Black Head, a dark promontory about 60 metres high, separates Possession Bay from Cook Bay to the north.

Brighton Beach was named by Discovery Investigations personnel during their 1926–30 survey of South Georgia, after the English seaside resort of Brighton, because the strand was as crowded with seals as Brighton is with holidaymakers. Nearby Alert Point was named for the expedition's survey motorboat Alert, and Zero Point and Black Head appear on charts from the same survey.

Discovery Investigations personnel named the beach during their 1926–30 survey, comparing its crowds of seals to the tourists of Brighton, the English seaside resort. The name first appears on charts from that expedition, alongside Zero Point and Black Head.

Access to this location comes only through organized expedition cruises operating during the Antarctic summer months between November and March. Visitors should prepare for rough ocean and weather conditions, bringing appropriate gear for these remote waters.
