Count Michał Tyszkiewicz (Lithuanian: Mykolas Tiškevičius) (4 December 1828 in Wołożyn – 18 November 1897 in Rome) was a Polish-Lithuanian nobleman collector of antiquities and amateur Egyptologist. He was a member of the Polish Tyszkiewicz family. He first excavated at Luxor in 1861–1862 and revisited Egypt in 1867–1868, building up a collection during his travels. It is now split between different locations in Lithuania, Paris, London, Copenhagen, Berlin, Boston, Rome, and the Tyszkiewicz Palace at Lahojsk, Belarus. A small part of it remains in Poland in the National Museum in Warsaw.
