HMS Alert was a 17-gun wooden screw sloop of the Cruizer class of the Royal Navy, launched in 1856 and broken up in 1894. She was the eleventh ship of the Royal Navy to bear the name (or a variant of it), and was noted for her Arctic exploration work; in 1876 she reached a record latitude of 82° North. Alert briefly served with the US Navy, and ended her career with the Canadian Marine Service as a lighthouse tender and buoy ship.
