(Amersfoort, c. 1601 - Amersfoort, 10 August 1669) was a Dutch painter.
Bor was descended from a notable Catholic family. He made a study trip to Rome, where he was one of the founders of the Bentvueghels, taking the nickname Orlando. He returned in 1626 to Amersfoort and joined Jacob van Campen in the decoration of the palace Honselaarsdijk belonging to Frederik Hendrik. In 1656, he became regent of the godshuis "De Armen de Poth" in Amersfoort.
Bor's style of painting was rather at odds with that of contemporary painters from Utrecht. He initially painted rather Caravaggisti-like history paintings, but his works fast became marked by a classicism related to that of his townsman van Campen. Through unusual compositions and primitive technique, his paintings depict strange and mysterious subjects.
