Flash floods occurred throughout the Indonesian capital of Jakarta and its metropolitan area on the early hours of 1 January 2020, due to the overnight rain which dumped nearly 400 millimetres (15 in) of rainwater, causing the Ciliwung and Cisadane rivers to overflow. At least 66 people have been killed, and 60,000 displaced in the worst flooding in the area since 2007.

The 2007 Jakarta flood was a major flood in Jakarta, the capital of Indonesia and affected several other areas around the city, such as West Java and Banten. The flood, beginning on February 2, 2007 was a result of heavy rain, deforestation in areas south of the city, and waterways clogged with debris. The flood is considered the worst in the last three centuries, including the 1996 and 2002 Jakarta floods, which killed 10 and 25 people respectively.
