Defiance was a French vessel that first appeared in Lloyd's Register in 1803 with N.Long, master, Gibbons & Co., owners, and trade London–South Seas.

She sailed for the South Seas on 7 December 1802, but immediately put into Ramsgate, having sustained damage when she ran on to the Brake.

[2] She was driven ashore and wrecked on the coast of France in late December 1802.

Captain Nathan Long (of Nantucket), her mate, and seven other crew drowned; 21 crew survived.

[3][4][5] It is highly likely that this Defiance is the Defiance that made three voyages as a slave ship and that a privateer captured in late 1800.
