USS Hyacinth was a steamer acquired by the Union during the American Civil War.

She captured Confederate transport Sovereign near Fort Pillow, Tennessee, 5 June 1862; and 9 days later, took steamer Clara Dolsen after a long chase from Helena, Arkansas, ending on the White River a short distance above its mouth.

Spitfire was transferred by the U.S. War Department to the Union Navy 30 September 1862, and renamed Hyacinth 19 October.

She was especially useful in operations which resulted in the fall of Vicksburg, and assisted in the salvage work which refloated Indianola.
