Malaysian South-South Corporation Berhad (MASSCORP) is a public limited company incorporated in 1992. MASSCORP is a consortium of 86 Malaysian shareholders, many of whom are corporate leaders in their respective fields of business who have contributed immensely to the national economy.

Like its sister organisation, Malaysia South-South Association (MASSA), the company's origins can be traced to the successful 1991 trade mission to Latin America by former Prime Minister Tun Dr. Mahathir Mohamad.
