Segun Osoba (born 1941) was governor of Ogun State from January 1992 until November 1993. He was elected on the Social Democratic Party (SDP) platform, and was removed from office by the administration of General Sani Abacha. After the return to democracy in 1999, he was elected again as governor on the Alliance for Democracy (AD) platform, holding office between May 1999 and May 2003. Since the completion of his second period of service in 2003, he has come to be referred to in the Nigerian popular press as Aremo due to his holding of the aristocratic title of Aremo Awujale of the Ijebus, though he also serves as a titled chieftain of the Egba clan as well.
Segun Osoba started a career in journalism in the 1960s, rising through the ranks to become Editor and Managing Director of the Daily Times of Nigeria. At one time he was the Managing Director of Sketch Newspaper.
In October 2004 he was picked up by the police in Lagos in connection with an attack by students of the Federal Polytechnic, Ilaro, on then Governor Oloye Gbenga Daniel of Ogun State. He was later released on bail.
