Abi Kusno Nachran (1940 in Kalimantan, Borneo, Indonesia - July 24, 2006) was an Indonesian rainforest preservation activist.
After dropping out of school, he worked in the municipal government of Pangkalanbun, where he participated in the widespread corruption and was also involved in the cover-up of illegal logging operations.
As a journalist, he wrote articles against forest destruction and made inquiries against illegal loggers and dealers.
To come up with the €15,000 for the operation, Nachran sold his property and got the remainder from donors, with the hospital waiving a portion of the fee.
On 24 July 2006, Abi Kusno Nachran was killed in a traffic accident in Cirebon and died at the age of 64.
