Warren Delano Jr. (July 13, 1809 – January 17, 1898) was an American merchant and drug smuggler who made a large fortune smuggling illegal opium into China.

[1] After his mother's death in 1827, his father, who was involved in the New England sea trade, remarried to Elizabeth Adams,[2] a widow of Captain Parker of the United States Navy.

Earlier, John Perkins Cushing – also a Russell & Company partner – had worked with the largest Chinese hong merchant, Howqua, to establish an offshore base.

At this anchored floating warehouse, Russell & Company ships would offload their opium contraband, then continue with their legal cargo up the Pearl River Delta to Canton.

Together, they were the parents of eleven children:[7] In 1851, Delano bought 60 acres on the Hudson River in Balmville, New York (two miles north of Newburgh).

He commissioned Andrew Jackson Downing and Calvert Vaux to remodel an existing farmhouse into an Italianate villa, naming it Algonac.
