Pierre Jean van der Ouderaa (1841–1915) was a Belgian painter and lithographer of religious subjects, genre scenes, portraits, and landscapes.

[1] In 1865 he came second in the Grand Prix de Rome, and was awarded a three year travel bursary, funded by the Belgian government, to study the paintings of Raphael in Italy.

[1] In search of the exotic, he accompanied Albert Cogels (1842–84) on a trip to Algiers, Tunis, Oran and Spain.

He produced "romantic fantasies" in the style of Hendrik Leys and de Keyser, and the large-scale historical compositions for which he became known.

In 1890 he painted the Academic triptych Jean Berchmans Lying in State for Antwerp Cathedral.
