Council of Nigerian Mining Engineers and Geoscientists (COMEG) is the regulatory body for all professionals and firms in the Geosciences, Mining Engineering and Metallurgy in Nigeria. COMEG was established through Act No. 40 of 1990 (now Act CAP C33 LFN, 2004) and was inaugurated on 12^th September, 2000.

The President of the Federal Republic of Nigeria performed the inaugural Registration Ceremony of COMEG and presented the instruments of registration and practice to the Chairman of the Council on 30th January 2003.

Its major thrust is to regulate and control the practices of professionals in the fields of geology, geophysics, geochemistry, mining engineering, petroleum engineering, metallurgy, etc. These professionals through their practices contribute to Nigeria's foreign exchange earnings annually. COMEG's regulatory responsibilities are targeted at the extractive industries, which undoubtedly constitute the backbone of the nation's economy. By definition, the mining engineering professions include mining engineers, petroleum engineers, metallurgists and their corresponding technologists; while geoscientists include geologists, geophysicists, geochemists, hydrologists etc.

The regulatory functions of COMEG cover professionals and firms in the solid minerals, petroleum, water resources, power and steel, and environment sectors. By law, the Ministry of Mines and Steel Development is the supervisory Ministry of COMEG.
