Presidential elections were held in São Tomé and Príncipe on 17 July 2016. Initial results suggested Evaristo Carvalho of Independent Democratic Action had been elected in the first round of voting, defeating incumbent President Manuel Pinto da Costa; however, the results was subsequently annulled, necessitating a second round between Carvalho and Pinto da Costa, which was held on 7 August. However, Pinto da Costa boycotted the second round after claiming the first round had been fraudulent, meaning Carvalho was elected unopposed.

São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is an island country in the Gulf of Guinea, the western equatorial coast of Central Africa.
