The Nigerian Navy Secondary School Abeokuta, is a secondary school located in Abeokuta, Ogun State, Nigeria. It was founded in 1990 but the first set of students resumed on 2 March 1991.
As at 1990, it became evident that the children of personnel seeking admission in the only secondary school of the Nigerian Navy at Ojo was becoming too large for the school. Many states were contacted by the Nigerian Navy on assistance for a site. The then Governor of Ogun State, a naval personnel himself, Navy Captain Mohammed Lawal, invited the Nigerian Navy to consider a location of the defunct St Leo's Teachers' Training College at Ibara Abeokuta (www.nnssab.net)on a hilly Onikolobo site. This premises had been abandoned and merely serve as a route to the Catholic Compound and was also used for administering a newly conceived secondary school in that name. The Nigerian Navy considered the site and found it suitable. A team of officers headed by Commodore SO Lawuyi, the Chief of Naval Education, Lt Cdr SEA Olamilokun, SO 1 Education at Naval Headquarters, SLt Nelson Demebide and a civilian architect, were sent to receive the compound. The team took inventories of the facilities at the site and made recommendations for its renovations.
Nigerian Navy Secondary School, Abeokuta was founded on 2 February 1991 and is sited at the former St Leo's Teachers' College at Ibara Abeokuta, Ogun State of Nigeria. At the handing over ceremony on that day, the Ogun State Military Governor, Navy Captain Oladeinde Joseph, commended the Nigerian Navy for bringing a model secondary school to Abeokuta. The then Chief of the Naval Staff, Admiral Murtala Nyako implored the school to train the children who would excel in all. He emphasized that the Nigerian Navy Secondary School Abeokuta, although a civilian secondary school, should be seen as the Nigerian Navy's equivalent of a military school and should be run as such.
The school started with 623 students admitted into Junior Secondary 1 and Junior Secondary School 2. The pioneer commandant was Lieutenant Commander SEA Olamilokun who took over command of the school on 20 November 1990. The first Executive Officer was Lieutenant SJ Ajiboye. Some of the pioneering staff were Mrs OA Okunneye, Miss Nwogbo, Mr Osinowo, Mr. Oladele and Mr Agoreyo. Other members of staff were SLt Chukwu, Mrs Salako, Miss Ajimati and Mr Adesanya.
