Baron Sándor Hatvany-Deutsch (12 November 1852 – 18 February 1913) was a leading Hungarian Jewish industrialist, business magnate, philanthropist, investor and art patron.

He founded in 1902 with Ferenc Chorin the National Alliance of Industrialists (Gyáriparosok Országos Szövetsége (GYOSZ)) and was the first vice president of the association.

After his studies, Sándor Deutsch de Hatvan joined the family trading business, and with the help of his cousins, made it into a major player in the sugar industry.

Sándor Hatvany-Deutsch participated in the creation of the National Association of Hungarian Industrialists in 1902, supported hospitals and sponsored a theater in Budapest.

His son Baron Ferenc Hatvany would accumulate Hungary's most valuable collection of paintings before it was seized by the Nazis during World War II.
