Leslie Thomas Manser, VC (11 May 1922 – 31 May 1942) was a British bomber pilot and a recipient of the Victoria Cross, which was awarded posthumously following an attack on the German city of Cologne.

Leslie Thomas Manser was born in New Delhi, India, during his father's employment as an engineer with the Post and Telegraph Department and, when the family returned to Britain, they settled in Radlett, Hertfordshire.

Participating in Operation Millenium, a bombing raid on Cologne on the night of 30 May 1942, Manser was captain and first pilot of Avro Manchester bomber 'D' for Dog.

As the crew parachuted down they saw the bomber crash in flames into a dyke at Bree, Belgium, 13 mi (21 km) north east of Genk.

In pressing home his attack in the face of strong opposition, in striving, against heavy odds, to bring back his aircraft and crew and, finally, when in extreme peril, thinking only of the safety of his comrades, Flying Officer Manser displayed determination and valour of the highest order.Manser is buried at the Heverlee War Cemetery in Leuven, Belgium.
