Lucio Massari (22 January 1569 – 3 November 1633) was an Italian painter of the School of Bologna.

In 1607, he collaborated with Lionello Spada and Francesco Brizio in frescoes for the Palazzo Bonfioli, in Bologna.

In 1612, he completed the frescoes left unfinished by Bernardino Poccetti in a chapel of the Certosa di Galluzzo, near Florence.

He painted the main altarpiece for the church of Santa Maria in Guadi in San Giovanni in Persiceto.

He is said to have spent so much time in hunting, fishing, and the delights of the countryside, that he neglected painting, though his biography shows him to be exceedingly prolific in altarpieces.
