Six ships of the British Royal Navy have been named HMS Invincible.

The fifth Invincible of the Royal Navy was a battlecruiser, the lead ship of her class of three, and the first battlecruiser to be built by any country in the world.

HMS Invincible was an Audacious class ironclad battleship of the Royal Navy. She was built at the Napier shipyard and completed in 1870. Completed just ten years after HMS Warrior, she still carried sails as well as a steam engine.
