Some parts of Africa are well-known as places where old Russian aircraft find their last home. Nigeria is one of the exceptions. There is no carrier that currently operates Russian aircraft nor have there been many in the past. Nigeria never had a strong focus on the Soviet Union. And in the 1990s, when many private airlines were established in Nigeria, it was probably easier and cheaper to get secondhand aircraft from Europe and the United States.
Here is a list of Nigerian Airlines that leased or owned Russian metal:

Other airlines that operated Eastern European made aircraft were Oriental Airlines with a LET L-410 (late 1980s) and Lamonde Air that had two of this type (5N-BEA and 5N-BEB) in the 2000s. 5N-BEB was later registered as 5N-BCM and operated by Easy Link Aviation.
