Robert Christiaan Noortman (5 March 1946 – 14 January 2007) was a Dutch art dealer.
Noortman, born in Heemstede opened his first gallery in Hulsberg. In 1974 he expanded to London and later also towards Maastricht and New York City. In 1980 he would move his Hulsberg gallery to Maastricht and merge it with the already existing gallery there, while he closed his foreign galleries. In June 2006 he sold his last gallery for 44 million euros and still remained in function as a director.
For fun Noortman studied for and graduated as a commercial pilot and later flew through twelve European countries in one single day by daylight. This record was named in the Guinness Book of Records.
Noortman suffered from osteoarthritis and cancer, but died because of a myocardial infarction on 14 January 2007 in Kuttekoven, two days after he received an award from the city of Maastricht for his positive influence on Maastricht and its area. Earlier in his life he already won the title of "Honorary Liveryman of the City of London" and the " Chevalier de l’Ordre des Arts et des Lettres" in France.
