HMS Commonwealth, was a King Edward VII-class battleship of the British Royal Navy. Like all ships of the class (apart from HMS King Edward VII) she was named after an important part of the British Empire, namely the Commonwealth of Australia. After commissioning in 1905, she served with the Atlantic Fleet until she was involved in a collision with HMS Albemarle in early 1907. While being repaired, she was transferred into what would become known as the Home Fleet. Following a reorganisation of the fleet in 1912, she, along with her King Edward VII-class sister ships formed the 3rd Battle Squadron, which served in the Mediterranean.
