USS Oleander was a wooden screw steamer acquired by the United States Navy for service during the American Civil War. The vessel was built in 1863 at New York City and was purchased by the Navy in November of that year. She was commissioned in early 1864 and assigned to the North Atlantic Blockading Squadron, where she performed supply, transport, and dispatch duties in support of the Union blockade of Confederate ports along the Atlantic seaboard, particularly off Virginia and North Carolina.
After the cessation of hostilities, USS Oleander was decommissioned in June 1865 and subsequently sold at public auction later in the same year.
