Darlene Keju, also known as Darlene Keju-Johnson, (1951 – June 18, 1996) was a Marshallese activist. She was born on Ebeye Island in the Marshall Islands group in 1951. The Northern Islands where she grew up were downwind from Bikini and Enewetak atolls where the United States tested 67 nuclear weapons. She witnessed the evacuation of Regelap and Utirik Atolls after they were contaminated by radioactive fallout. Keju is credited for bringing to the attention of the world the suffering of the Marshall Islanders as a result of the nuclear testing and that many more people were affected than acknowledged by the U.S. government.
