The following lists events that happened during 2020 in West Africa.

Piracy in the Gulf of Guinea affects a number of countries in West Africa as well as the wider international community. By 2011, it had become an issue of global concern. Pirates in the Gulf of Guinea are often part of heavily armed criminal enterprises, who employ violent methods to steal oil cargo. In 2012, the International Maritime Bureau (IMB), Oceans Beyond Piracy and the Maritime Piracy Humanitarian Response Program reported that the number of vessels attacks by West African pirates had reached a world high, with 966 seafarers attacked during the year. According to the Control Risks Group, pirate attacks in the Gulf of Guinea had by mid-November 2013 maintained a steady level of around 100 attempted hijackings in the year, a close second behind the Strait of Malacca in Southeast Asia.
