The sinking of Rainbow Warrior, codenamed Opération Satanique, was a "covert operation" by the "action" branch of the French foreign intelligence agency, the Directorate-General for External Security (DGSE), the covert attack was carried out on 10 July 1985. During the operation, two operatives (both French citizens) sank the flagship of the Greenpeace fleet, Rainbow Warrior, at the Port of Auckland on her way to a protest against a planned French nuclear test in Moruroa. Fernando Pereira, a photographer, drowned on the sinking ship.

The sinking was a cause of embarrassment to France and President François Mitterrand. They initially denied responsibility, but two French agents were captured by New Zealand Police and charged with arson, conspiracy to commit arson, willful damage and murder. It resulted in a scandal that led to the resignation of the French Defence Minister Charles Hernu, while the two agents pleaded guilty to manslaughter and were sentenced to ten years in New Zealand prison. Despite being sentenced to ten years' imprisonment, due to pressures from the French state they spent merely two years confined to the French Polynesian island of Hao before being freed by the French government.

France was also forced to apologise and had to pay reparations to New Zealand, Pereira's family and Greenpeace.

France began testing nuclear weapons in 1966 on Mururoa Atoll in the Tuamotu Archipelago of French Polynesia. In 1985, the South Pacific nations of Australia, the Cook Islands, Fiji, Kiribati, Nauru, New Zealand, Niue, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu signed the Treaty of Rarotonga declaring the region a nuclear-free zone.

Since being acquired by Greenpeace in 1977, Rainbow Warrior was active in supporting several anti-whaling, anti-seal hunting, anti-nuclear testing and anti-nuclear waste dumping campaigns during the late 1970s and early 1980s. Since early 1985, the ship was based in the southern Pacific Ocean, where its crew campaigned against nuclear testing. After relocating 300 Marshall Islanders from Rongelap Atoll, which had been polluted by radioactive fallout by past American nuclear tests, it travelled to New Zealand to lead a flotilla of yachts protesting French nuclear testing at the Mururoa Atoll.

During previous nuclear tests at Mururoa, protest ships had been boarded by French commandos after sailing into the shipping exclusion zone around the atoll. For the 1985 tests, Greenpeace intended to monitor the impact of nuclear tests and place protesters on the island to monitor the blasts.

French agents, posing as interested supporters or tourists, toured the ship while it was open to public viewing. DGSE agent Christine Cabon, who had previously worked on intelligence missions in the Middle East, posed as environmentalist "Frederique Bonlieu" to infiltrate the Greenpeace office in Auckland. While working for the Auckland office, Cabon secretly monitored communications from Rainbow Warrior, collected maps and investigated underwater equipment.

Three agents on board the yacht Ouvéa imported the limpet mines used for the bombing. Two more agents, Dominique Prieur and Alain Mafart, posing as the newlywed couple "Sophie and Alain Turenge", picked up the mines and delivered them to the bombing team, consisting of the divers Jean Camas ("Jacques Camurier") and Jean-Luc Kister ("Alain Tonel").
