Piotr Michalowski (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 (since 1853).
The Sukiennice Museum, a division of the National Museum in Kraków, contains a room that is named after him and devoted to Michalowski's work.
