Leslie Gordon Knight, DSO (7 March 1921 – 16 September 1943) was an Australian bomber pilot in the Royal Australian Air Force during the Second World War. He was awarded the Distinguished Service Order in 1943 for his role in Operation Chastise while flying with No. 617 Squadron RAF. Knight's crew, flying in N-Nan, attacked, hit and breached the Eder Dam, the second dam to be attacked, after his comrades had previously scored one hit and one miss. In the 1955 film The Dam Busters, Knight was played by Denys Graham.
