This is a list of aviation-related events from 1914.

The outbreak of World War I accelerates all aspects of aviation which in turn changes war in a twofold way. The aeroplane turns the sky into a new battlefield and eliminates the distinction between frontline and hinterland, with the civilian population far behind the frontline also becoming a target. The war results in the deaths of approximately 20,000 flyers, most of them trained pilots.
