John Ngu Foncha (21 June 1916 – 10 April 1999) was a Cameroonian politician, who served as 5th Prime Minister of Cameroon.
He founded the Kamerun National Democratic Party (KNDP) in 1955 and became Premier of the British Cameroons on 1 February 1959.
He held that position until 1 October 1961, when the region, renamed West Cameroon, merged into a federation with Francophone Cameroon.
From 1 October 1961 to 13 May 1965, Foncha concurrently served as 5th Prime Minister of Cameroon and Vice-President of the Federal Republic of Cameroon.
In 1994, he led a delegation of the Southern Cameroons National Council (SCNC) to the United Nations to request its backing of the movement's drive for greater autonomy in Cameroon's two English-speaking provinces.
