The 1st Royal Naval Brigade was an infantry brigade of the Royal Navy which was formed from excess naval reserve personnel. The brigade was formed in August 1914 and assigned to the 63rd (Royal Naval) Division after that division's formation in September 1914 and served on the Western Front and during the Gallipoli campaign, until July 1916 when it was broken up. The brigade was formed once more for a few days, but once again disbanded following the division's absorption into the Army's order of battle.
