John Idowu Conrad Taylor (24 August 1917 – 7 November 1973) was a Nigerian jurist, Judge of the Supreme Court of Nigeria (1964 to 1967), and the first Chief Justice of Lagos State (1967 to 1973).
He left for England in 1929 where he completed his secondary education at Culford School in Bury St. Edmunds, between April 1929 and July 1936.
He graduated with a second class degree in the Honour School of Jurisprudence and was subsequently called to the Bar at the Middle Temple on 14 January 1941.
Taylor had a swift rise through the Nigerian legal ranks, culminating in appointment as a Judge of the High Court, Western Nigeria, at the age of 39.
Upon his death, the Nigerian Head of State, General Yakubu Gowon, delivered a speech in which he said: "In an age which corruption, intrigues back biting and the love of office and power are fast becoming a virtue, Mr. Justice Taylor stood out from the crowd with a detachment that has brought immense dignity to the High Office of a Judge".
