Brigadier General Frank Percy Crozier, CB, CMG, DSO (1 January 1879 – 31 August 1937) was a British Army officer. His first military experience was in the Second Boer War (1899–1902) and with the Royal West African Frontier Force in Nigeria. During the First World War, he commanded the 9th (Service) Battalion of the 107th (Ulster) Brigade in the Battle of the Somme, earning him the promotion to brigadier general and command of the 119th (Welsh) Brigade in the Battle of Cambrai and German spring offensive.
After the war, he briefly served as an advisor of the newly established Lithuanian Army and commander of the Auxiliary Division of the Royal Irish Constabulary at the time of the Partition of Ireland. However, he quickly became disillusioned with the conduct of the auxiliaries during the conflict. Crozier became a pacifist and published several controversial autobiographical books.
