The 2016 Vietnam marine life disaster was a water pollution crisis affecting Hà Tĩnh, Quảng Bình, Quảng Trị and Thừa Thiên–Huế provinces in central Vietnam. Fish carcasses were reported to have washed up on the beaches of Hà Tĩnh province from at least 6 April 2016. Later, a large number of dead fish were found on the coast of Hà Tĩnh and three other provinces (Quảng Bình, Quảng Trị and Thừa Thiên–Huế) until 18 April 2016. Formosa Ha Tinh Steel, a steel plant built by the Taiwanese corporation Formosa Plastics, discharged toxic industrial waste illegally into the ocean through drainage pipes. After denying responsibility for months, Formosa accepted responsibility for the fish deaths on 30 June 2016.
