Gerriet Postma (30 October 1932 – 27 February 2009) was a Dutch painter.
His last large-scale work comprised four panels, painted on the four main sails of the traditional and historic cargo barge "Klipper Anna".
The 106-year-old ship was provided by its owners, Gijs en Inge van Hesteren from Harlingen, Friesland, the Netherlands.
All summer long in 2004, the painting could be seen everywhere around the Dutch Wadden Sea.
His work is on display in galleries of Paris, Brussels and Barcelona.
