Matteo Pietro Olivero (15 June 1879 - 28 April 1932[1]) was an Italian painter, known for his technique of reproducing sunlight reflections without physically mixing colour pigments.

For that matter he is considered a leading painter of the Italian divisionism, although he's still little-known outside the art collector's environment.

During his life, he took part in several exhibitions across Europe and started a collaboration with "Les Tendances Nouvelles", a Parisian art journal.

After a visit to a St. Moritz exhibition, he became a close friend of the painter Giuseppe Pellizza da Volpedo, with whom he started a written correspondence and, afterwards, a collaboration.

Luigi Burgo, a local businessman and owner of a paper mill, took Olivero under his custody, hosting him in his house and becoming his patron.
