Carlos Carmelo Vasconcellos Motta (16 July 1890 in Bom Jesus do Amparo, archdiocese of Mariana, Minas Gerais, Brazil – 18 September 1982 in Aparecida, São Paulo, Brazil) was a long-serving cardinal.
Until Eugênio de Araújo Sales surpassed him in 2005, he was the longest-serving Brazilian cardinal, and during his cardinalate the Church in Brazil underwent tremendous expansion, involving the development of many new movements that were to develop after he had largely disappeared from the scene.
