Enyimba, known as 'The People's Elephant' by fans, were held to a goalless draw by closest rivals Warri Wolves on Sunday to reach an unassailable 69 points in the Nigeria Premier League.
Despite playing a man short after forward Daniel Etor was sent off in the 50th minute for punching an opponent, the home team held out in front of a record 40,000 fans at the Enyimba International Stadium in Aba, southeast Nigeria. Enyimba last won the league in 2010.
"We are happy that we have won the league again. As a coach, I am happy and I commend the players for their commitment," the veteran coach said.
He added: "We must now re-group and come back stronger next season."
