Bilateral relations between the Federal Republic of Nigeria and the United States of America were formally inaugurated when Nigeria attained its independence from Britain in 1960. In the 21st century, they have entailed an important, if occasionally uneasy, alliance, following a more chequered diplomatic past. Nigeria has traditionally been among the United States's most important partners in Africa, and together the countries' populations account for more than half a billion people. According to a 2019 poll from Pew Research Center, 62% of Nigerians had favorable views of the United States.
