The CQ Manchester Mineira DX Contest (CQMM DX Contest) is a continuation of the popular and successful Manchester Mineira All America CW Contest, being organized and established by the Group CWJF since 1993. The competition was initially limited to Brazil (1993-1996), later expanded to South America (1997-2006) and finally extended to the Americas (2007-2010). From 2011, it becomes an international competition held among all continents.

The city of Juiz de Fora is so-called "Manchester Mineira" (The Manchester of the State of Minas Gerais) for being one of the most industrialized cities in Latin America.
