Mohamed Ibn Chambas (born 7 December 1950 in Bimbilla,[1] Ghana) is a Ghanaian lawyer, diplomat, politician and academic who has served as an international civil servant since 2006.

He led Ghana's delegation to the UN General Assembly, ministerial meetings of the OAU and the Economic Community of West African States (ECOWAS), the Non-Aligned Movement, and the Commonwealth.

Centrally involved in the ECOWAS mediation efforts in Liberia, he directly participated in negotiations leading to the agreements ending the Liberian civil war.

In the interim, Chambas lost his Parliamentary seat in 1996, and the then government of President Jerry Rawlings removed him from the foreign ministry and put him in charge of Ghana's primary education system.

In that capacity, he had direct responsibility for the country's five universities, 10 polytechnics and agencies/institutions charged with formulation of policies on higher education, accreditation and maintenance of standards in tertiary institutions.

He also led negotiations and conflict resolution processes during student protests and industrial disputes involving university and polytechnic teachers and other staff members.

Chambas was at the time suggested in the Ghanaian press as a candidate for the New Patriotic Party (NPP).Regaining his seat in 2000, he was also a member of the Commonwealth Ministerial Action Group, which worked to facilitate a transition to constitutional democratic governance in Nigeria, Sierra Leone and the Gambia.
