Frans Thomas Koppelaar (born April 23, 1943) is a Dutch painter, who was born in The Hague, Netherlands.

From 1963 to 1969, he attended the Royal Academy of Visual Arts at The Hague.

[1] His landscapes and Amsterdam cityscapes are painted in a style that recalls the classical tradition of the Hague School and the Amsterdam Impressionists.

[2] Koppelaar's work is congenial to a figurative movement in Dutch contemporary painting that evolved during the 1990s in a reaction to the pared-down conceptual art and the too pompous art-theories of that period.

Through the years his style evolved into a simpler, straightforward approach.
