A steamboat or steamship, sometimes called a steamer, is a ship in which the primary method of propulsion is steam power, typically driving propellers or paddlewheels. Steamships usually use the prefix designation SS, S.S. or S/S.

The term steamboat is usually used to refer to smaller steam-powered boats working on lakes and rivers, particularly riverboats; steamship generally refers to larger steam-powered ships, usually ocean-going, capable of carrying a (ship's) boat. The term steam wheeler is archaic and rarely used. In England, "steam packet", after its sailing predecessor, was the usual term; even "steam barge" could be used, especially in newspaper reports. Steam engines were developed and adapted in the late 18th century for use on ships, but did not become widely used until the early 19th century. Growth in their use was rapid on United States rivers, and seaworthy steamships graally replaced sailing ships for commercial shipping through the latter 19th century. During that period even the largest of steamships had auxiliary sails.[notes 1] The French transatlantic steamer "La Touraine" was probably the last of her type to be equipped with sails, although she never used them. Steamships in turn were overtaken by diesel-driven ships in the second half of the 20th century. Most warships used steam propulsion from the 1860s until the advent of the gas turbine in the early 20th century.
