Cornelis de Man (Delft, 1 July 1621 - Delft, 1 September 1706) was a Dutch Golden Age painter.
Kornelis was not satisfied with life in Delft. He wanted to travel beyond the port of Dordrecht and that is what he did, spending a year in Paris as soon as he came of age and had enough talent to pay his way with his painting skills. He was well-received, but set off in the Spring for Lyon in order to cross Lombardia and the mountains before another winter set in. He settled for two years in Florence, where he had a rich patron, but stayed the longest in Rome. On the way back home he stopped in Venice, and in the end was gone for a total of nine years Ferdinand Lepie painted River by night in 1872
