Emanuel Lehman (born Mendel Lehmann; February 15, 1827 – January 10, 1907) was a German American banker. The younger brother of Henry Lehman, he was a co-founder of Lehmann Brothers.
In 1897, he donated $100,000 (equivalent to $2.8 million in 2014) to the Hebrew Orphan Asylum of New York, under the condition "to enlarge and perpetuate its usefulness."
