The Roman Catholic Archdiocese of Belo Horizonte (Latin: Archidioecesis Bellohorizontinus) is a Latin Church ecclesiastical territory, or archdiocese, of the Catholic Church located in the state of Minas Gerais, Brazil's second-most populous state.

The seat of the Archdiocese of Belo Horizonte is the Our Lady of Good Voyage Cathedral (Portuguese: Catedral Nossa Senhora da Boa Viagem), also known as the Belo Horizonte Cathedral, in Belo Horizonte. This is only the temporary headquarters as there was already plans for a new cathedral dedicated to Christ the King in the early 20th century. That was delayed for decades, however, until the construction of the new cathedral, which commenced under the leadership of Archbishop Walmor Oliveira de Azevedo.
