USS Poppy was a steamer commissioned by the Union Navy during the American Civil War.

During the Civil War, Poppy served as a ship's tender to the North Atlantic Blockading Squadron.

On the night of 8 April a small boat succeeded in attacking frigate USS Minnesota, flagship of the North Atlantic Blockading Squadron, with a torpedo, making a clean escape.

Poppy was then used as mail and supply tug until 17 June when she was stationed in the James River above Wilson’s Wharf as a tender and ram to ironclads.
