Kyuka Lilymjok (also known as Adamu Kyuka Usman and Adamu Lilymjok; born 24 September 1965, Bafoi-Kanai, Nigeria) is a Nigerian writer,[2] political thinker, philosopher,[3] and professor of law at Ahmadu Bello University (ABU), Zaria, Nigeria.

After the final judgement was passed in favour of the incumbent president and the PDP, he published a critique to show his displeasure in the ruling, titled: Buhari Vs Obasanjo: Law and Justice on the Cross.

[citation needed] When Buhari moved to the newly formed All Progressives Congress (APC) in which he was to contest for the fifth consecutive time against the incumbent president, Dr. Goodluck Ebele Jonathan, GCFR, Lilymjok's alliance followed suit and was a core member of the new party and supporter of the man he so admired.

[citation needed] He served as Deputy Director of the Policy, Research and Strategy Committee of the council in the 2019 presidential polls in which now President Buhari was contesting for a second term in office, and served also as the APC Returning Officer for Kaduna State in the 2019 gubernatorial elections in which Nasir Elrufai ran for re-election[13] and was reported to have won, even though the issue was strongly contested in court by the PDP candidate, just as in the case of the presidential election.

Adamu Kyuka Usman has many works of fiction in his name and he was one of the two Association of Nigerian Authors (ANA)/Jacaranda literary prize award winners for Prose through his book Sieged, in the year 2011.
