The 63rd (Royal Naval) Division was a United Kingdom infantry division of the First World War. It was originally formed as the Royal Naval Division at the outbreak of the war, from Royal Navy and Royal Marine reservists and volunteers, who were not needed for service at sea. For RN personnel, the designation HMS Victory IV was used. The division fought at Antwerp in 1914 and at Gallipoli in 1915. In 1916, following many losses among the original naval volunteers, the division was transferred to the British Army as the 63rd (Royal Naval) Division, re-using the number from the disbanded second-line 63rd (2nd Northumbrian) Division Territorial Force. As an Army formation, it fought on the Western Front for the remainder of the war.
