HMS Orion is a designation that has been applied to several ships of the Royal Navy, all named after the constellation Orion. The name has been assigned to vessels of differing types and eras, notably a ship of the line, an armoured cruiser, and a battleship.
Ships of the Royal Navy named HMS Orion
| Launch year | Type / Class | Service highlights | Fate |
|---|---|---|---|
| 1848 | 91‑gun second‑rate ship of the line (later converted to screw propulsion) | Built at Portsmouth, entered service in the early 1850s. Converted to a screw‑driven vessel in 1855 and later used as a training ship. | Sold for scrap in 1909. |
| 1910 | Orion‑class dreadnought battleship | Commissioned in 1912, assigned to the Grand Fleet. Participated in the Battle of Jutland (1916) and other World War I operations. | Decommissioned in 1922; broken up in 1924. |

Note: The above list reflects the most historically documented vessels bearing the name HMS Orion. Other usages of the name (e.g., as a tender, depot ship, or in auxiliary roles) have been recorded in limited sources, but those instances lack the comprehensive documentation necessary for detailed encyclopedic entries.
Naming convention
The Royal Navy tradition of naming warships after mythological figures, constellations, and celestial bodies accounts for the selection of Orion, a prominent constellation associated with the mythic hunter of Greek tradition. The use of this name aligns with the broader pattern of employing astronomical names for capital ships during the late‑19th and early‑20th centuries.
Summary
- HMS Orion (1848) – a 19th‑century ship of the line, later a training vessel.
- HMS Orion (1902) – an armoured cruiser that saw service in World War I.
- HMS Orion (1910) – a dreadnought battleship that fought at Jutland and was decommissioned after the war.
Each vessel contributed to the operational capabilities of the Royal Navy during her period of service, reflecting the evolution of naval technology from sail‑powered ships of the line to steam‑driven armored cruisers and finally to steel‑hull battleships.
