Gbadamosi Adegoke Adelabu Listenⓘ (3 September 1915 – 25 March 1958) was a prominent personality in the politics of Ibadan city and subsequently that of the Western Region of Nigeria right before the country's independence in 1960.

His successful political career was cut short when he was killed in a car crash, not long before Nigeria gained independence from Britain.

He was offered employment by UAC as an assistant to the Ibadan district manager, an expatriate Adelabu had met a year earlier.

He was successful in his second stint with the organization but after the resignation of his mentor, the Ibadan District Manager Richardson, Adelabu left the firm.

At the time, the Ibadan Native Authority system was dominated by junior chiefs, family heads (mogaji) and the Olubadan, majority of whom were not literate.

Adelabu's career in politics can be traced to his support of the agitation led by junior chiefs and mogajis against Salami Agbaje.

The target of the chiefs was Salami Agbaje, a businessman who held the traditional title of Otun Balogun of Ibadan.

Adelabu was active in the movement to depose Agbaje, providing print commentaries and assisting in writing the petition that the chiefs forwarded to the colonial authorities.

During this period, Adelabu became secretary of the Egbe Omo Ibile, the leading association opposed to Agbaje and headed by Bello Abasi, the son of Aleshinloye, the previous Olubadan.

Adelabu capitalized on some anti-Ijebu sentiments among native Ibadan residents, especially after the loss of Oshun division, which was supported by Action Group leaders such as Awolowo (an Ijebu-man) and Akintola.

However, an informal alliance proposed by Adelabu to support NCNC fell apart and four of the elected members joined AG.

He opposed the district council terms of tax reform and the role of heads of lineages (mogajis) in governance, positioning himself as a supporter of traditional authority and values.

Hoping to lead the party to victory, he had ordered clothes with the inscription Adelabu, Premier of the Western Region.

[13] In 1958, Adelabu opposed the leadership of Azikiwe because of its support for a tripartite national government consisting of AG, NCNC and NPC.
