Gerardus "Geer" van Velde (5 April 1898, Lisse – 5 March 1977, Cachan, Paris) was a Dutch painter.
Van Velde was the second son of Willem Adriaan van Velde, then owner of a small case of inland waterway transport fuelwood and charcoal on the Rhine and Hendrika Catharina von der Voorst, illegitimate daughter of an earl.
Catharina and her four children (Neeltje, Bram, Geer, and Jacoba) were abandoned by Willem Adriaan after the bankruptcy of his business, leaving them in misery.
In 1910, at the age of twelve, Geer became an apprentice designer in the firm with Schaijk & Eduard H. Kramers.
Kramers encouraged Geer and his brother Bram van Velde to develop their interest in painting and funded both to a certain degree.
