Jan Porcellis (1580/84 Ghent – 29 January 1632 Zoeterwoude) was a Dutch marine artist in the seventeenth century. His works initiated a "decisive transition from early realism to the tonal phase", fostering a new style and subject in marine painting by focusing on overcast skies and rough waters, a radical break from maritime art's previous focus on the grandeur of ships in historical settings.
