Jozef Geirnaert, also known as Jozef Lodewijk Geirnaert, Théodore-Joseph-Louis Geirnaert and Joseph Louis Geirnaert (27 August 1790 in Eeklo – 20 March 1859 in Ghent), was a 19th-century painter and draughtsman from Belgium. He is known for his genre scenes, portraits as well as his historical, religious and mythological paintings. He was first influenced by the Neoclassical style of Jacques-Louis David and later by the version of Romanticism that was in vogue in Belgium from the 1830s.
