The 10th Battalion, Canadian Expeditionary Force was a Canadian field force unit created during the First World War. Technically distinct from the Militia from which its soldiers were drawn the unit served in the Canadian Expeditionary Force (CEF), specifically in the 1st Canadian Division from 1914 to 1919. The battalion participated in every major Canadian battle of the First World War, and set a record for the most decorations earned by a Canadian unit in a single battle at Hill 70. The unit was known to its contemporaries simply as The Fighting Tenth.

The 10th Battalion is perpetuated by The Royal Winnipeg Rifles and The Calgary Highlanders.

The Canadian Expeditionary Force was a separate entity created by Canada's Minister of Militia in 1914 for service to Britain in the First World War. Technically distinct from the standing land forces in existence at the time, soldiers were legally attested into the CEF in order to serve overseas. Hughes refused to mobilize the existing Militia units as units, and instead numbered battalions were created into which a combination of Permanent Force (regular) soldiers, Militia (reservists) and civilian volunteers were combined.

The Provisional 10th Battalion of the Canadian Expeditionary Force was created around cadres of Militiamen from two existing units; the 103rd Regiment (Calgary Rifles) and the 106th Regiment (Winnipeg Light Infantry). The unit was assembled at Valcartier in Quebec, and sailed for the United Kingdom with the first Canadian contingent in late 1914. Their commanding officer was Lieutenant Colonel Russ L. Boyle, a veteran of the war in South Africa and in 1914 the commander of the 15th Light Horse, an Alberta cavalry unit.

The unit trained on Salisbury Plain, and went into the trenches in France in early 1915 with the rest of the Division.
