Giovanni Battista Carlone (1603–1684) was an Italian painter of the Baroque period, active mainly in Genoa.
He came from a family of artists: his father Taddeo, uncle, and cousins were sculptors, and his older brother Giovanni Bernardo Carlone was a painter, trained in Rome and married to the daughter of Bernardo Castello.
His paintings throng local churches; for example, the Basilica della Santissima Annunziata del Vastato alone contains nearly 20 canvases and frescoes.
However his artistic profligacy also diluted the force of individuality in the paintings which, in style, seem to occupy an imprecise provincial talent between Mannerism and Baroque.
In the middle and principal nave of the Vastato, he has represented the Adoration of the Magi; the Entrance of Christ into Jerusalem; the Resurrection; the Ascension ; the Descent of the Holy Ghost; and the Assumption of the Virgin.
