Laura Gamble, ARRC (4 September 1887 – 1939) was a Canadian nurse who served in the Canadian Army Medical Corps during the First World War.

A 1910 alumna of the Toronto General Hospital School of Nursing, Gamble joined the Canadian Army Medical Corps as a nursing sister, enlisting on May 4, 1915.^[1] She expected that her experience in a Toronto hospital would be an asset to the war effort.^[2] She served on a hospital ship in the Mediterranean,^[3] and at hospitals in Greece, France, and the United Kingdom.^[4] She arrived on the Greek island of Lemnos after the Anglo-French force had already suffered heavy casualties as a result of the ill-fated Gallipoli campaign.^[5]

Canadian nurses were the only nurses of the British Empire's armies that held the rank of officers.^[2] Gamble was awarded the Royal Red Cross 2nd class in 1917 for her show of "greatest possible tact and extreme devotion to duty".^[2] This was presented to her at Buckingham Palace during a special ceremony for Canadian nurses.^[2][6] She also received the British War Medal and Victory Medal.^[7]

Gamble was recalled to Canada after the war and served as matron of St. Andrew's Military Hospital, Toronto. She was among the first nurses to take a new course in public health from the University of Toronto and worked for the Toronto Department of Public Health as Acting District Superintendent.^[5]

The diary Gamble kept during the war is conserved at the Library and Archives Canada in Ottawa.^[8]
