The 2020 Central Vietnam floods were a series of floods in Central Vietnam, which also affected some areas in Cambodia and Laos in October and early November 2020. The floods focused heavily in several provinces including Thừa Thiên Huế, Hà Tĩnh, Quảng Bình, Quảng Trị, and Quảng Ngãi. The floods were mainly caused by the seasonal monsoon, though enhanced by numerous tropical cyclones.

On 7 October, during a seasonal monsoon and tropical depressions over the Khánh Hòa province, several multitude of tropical cyclones during the 2020 Pacific typhoon season, such as Linfa, Nangka, Ofel, Saudel, and Molave, struck the northern and central regions of Vietnam, especially in areas of Laos and Cambodia, bringing high winds and excessive rainfall in these affected provinces, with accumulations peaked at 3,245 mm (127.8 in) in Hướng Linh, Hướng Hóa District, Quảng Trị around 20 October. This subsequent flooding was the first time Vietnam issued IV category disaster alert for heavy rainfall, as III category is the highest alert level.^[10]

On 5 November, the weakening Typhoon Goni entered the South China Sea and made landfall in Central Vietnam two days later as a tropical depression. Etau made landfall in Central Vietnam as a tropical storm three days later. On 12 November, Typhoon Vamco approached Vietnam as it gradually strengthened into Category 4-equivalent status after exiting the Philippine Area of Responsibility.

As of 1 December, over 243 people were reported by Vietnam Disaster Management Authority (VNDMA) as dead or missing due to the floods.^[11] The floods resulted in almost đ35.2 trillion (US$1.52 billion) of damages.
