Edmund Zaleski (18 August 1863 in Lviv (Lemberg), Austria-Hungary – December 1932 in Kraków, Poland) was a Polish chemist, agrotechnician, and plant breeder.
He was a professor at the Agricultural University of Dublany, as well as a professor (beginning in 1918) at Jagiellonian University, where he also served as rector from 1930–1931.
Zaleski created new, valuable varieties of wheat and sugar beet.
His book Metodyka doswiadczen rolniczych (Methodology of agricultural experiments) was published in 1927.
Professor Tadeusz Calinski of the Poznan University of Life Sciences credits him with the "first systematic lecture on the methodology of agricultural experiments with some application of probability theory."
