Count Michał Tyszkiewicz (4 December 1828, in Wołożyn – 18 November 1897, in Rome) was a Polish nobleman, collector of antiquities and Egyptologist.
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.
