Leonardo Coccorante was an Italian painter known for his capricci depicting imaginary landscapes with ruins of classical architecture.

Leonardo Coccorante was born in Naples, Italy. He studied or worked under Nicola Casissa, the Flemish landscape painter Jan Frans van Bloemen (1662–1749), Angelo Maria Costa (1670–1721), and finally with Gabriele Ricciardelli (active between 1741 and 1777). From 1737 to 1739, he was employed decorating the royal palace of Naples.

Coccorante died in Naples in 1750.

He is best known for his large highly detailed landscapes with imaginary classical architectural ruins. He often included small figures in the foreground to emphasize the expansiveness of the ruins. Coccorante is classified as a veduta (vista) painter.
