Barnabas Andyar Iyorhyer Gemade (born 4 September 1948) is a Nigerian politician who was former national chairman of the People's Democratic Party (PDP) and former senator.

[5] He succeeded Solomon Lar, the first chairman of the party, and was elected in part due to zoning rules which favoured allotment of the post to a northerner.

In a January 2011 interview, he described the turbulence in the leadership of the PDP in the early years as healthy, showing competition between individuals rather than a power-sharing arrangement between the different groups.

[6] In a November 2010 interview, Gemade supported the decision to allow incumbent President Goodluck Jonathan to run for election, despite the fact that some felt zoning rules meant the candidature should go to a northerner.

[9] In the 9 April 2011 elections for Senator of Benue North East, Gemade ran on the PDP platform and won against his primary opponent, Akaagerger, who had moved to the Action Congress of Nigeria.
