John Jacob Astor (born Johann Jakob or Johann Jacob Astor) (July 17, 1763–March 29, 1848) was the first prominent member of the Astor family and the first multi-millionaire in the United States. He was the creator of the first trust in America, from which he made his fortune in fur trading, real estate, and opium.

From humble origins in Germany, he emigrated to London and then to America following the American Revolutionary War. He built a fur-trading empire that extended to the Great Lakes region and Canada, and later expanded into the American West and Pacific coast. In the early 1800s he diversified into New York City real estate and later became a famed patron of the arts.
