Antonio Busca (1625–1686) was an Italian painter of the Baroque period, mainly active in Lombardy.
During 1648–9, under Procaccini, Busca along with Johann Christoph Storer, il Moncalvo, and Luigi Pellegrini Scaramuccia helped decorate of the Chapel of the Crucifix in the church of San Marco in Milan.
In 1650–51, he traveled to Rome to work with Giovanni Ghisolfi, and collaborated with him at the Sacro Monte of Varese.
Being much afflicted with the gout, he appears to have been unable to undertake anything with vigor; he sank into a mannered repetition.
