Count Michal Tyszkiewicz (Lithuanian: Mykolas Tiškevicius) (1828–1897) 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.
