Thomas Willeboirts Bosschaert (1613 – 23 January 1654) was a Dutch Republic-born Flemish Baroque painter.

Willeboirts Bosschaert was born in Bergen op Zoom, where his Catholic family had moved in the late sixteenth century.

[1] The artist ran his own studio with at least nine known pupils, and collaborated with other artists of the time such as Daniel Seghers, Paul de Vos, Jan Fyt, Jan van den Hoecke, Frans Snyders, and Adriaen van Utrecht, as well as with Peter Paul Rubens on the decoration series for Philip IV of Spain's Torre de la Parada (1636–1638).

Hendrik's widow, Amalia von Solms also commissioned a work from Willeboirts for the decorations of the Oranjezaal (Orange Room) in the Huis ten Bosch, a decorative program that included both Dutch and Flemish masters.

For one of these Seghers was awarded with a solid gold maulstick, and Willeboirts was given a hundred guilders.
