Martim Francisco Ribeiro de Andrada (21 February 1928 in Barbacena (MG) – 22 June 1982 in Belo Horizonte (MG)) was a Brazilian association football coach.
He is widely credited with the invention of the 4–2–4 formation when guiding his first club, the Villa Nova AC of Nova Lima, to the State Championship of Minas Gerais in 1951.
In his opinion, the WM of Herbert Chapman and the third defender of Izidor KĂĽrschner were the basis of all tactics.
He considered from early on the intermingling of club officials with the work of the coach as a major problem.
His bynames included primeiro lorde dos gramados brasileiros ("First Master of the Grounds of Brazil"), Professor and cientista do futebol ("Scientist of Football").
He died aged only 54 from alcohol related illness.
