Cecil van Haanen (1844-1914) was a Vienna-born Dutch portrait and genre painter, whose significant work was centred at Venice.
Van Haanen was the son to landscape painter Remigius Adrianus Haanen (1812–1894) and Emilie Mayer von Alsó-Rußbach.
He received early artistic training from his father and Friedrich Schilcher, and from April 1854 was educated at the pre-school of the Vienna Academy under Peter Johann Nepomuk Geiger.
