Piotr Michałowski (July 2, 1800 – June 9, 1855) was a Polish painter of the Romantic period, especially known for his many portraits, and oil studies of horses.
Broadly educated, he was also a social activist, legal advocate, city administrator and President of the Kraków Agricultural Society (starting in 1853).
He formally studied a broad range of subjects at the Jagiellonian University including classical philosophy, agriculture and mathematics.
While in Paris, he continued his studies of painting and anatomy with Nicolas Toussaint Charlet (1832–1835), greatly influenced by the art of Théodore Géricault, Rembrandt and Velázquez.
His watercolour studies of horses became very popular in France, sold by local art dealers since 1833 to English, German and American collectors.
