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.

If [however] one could set fire to London in thirty places, then what in a small way is odious would retire before something fine and powerful."^[53][54]
• 21 November – Three Royal Naval Air Service Avro 504s based at Belfort, France, conduct history's first long-range strategic bombing raid, attacking German airship sheds on the shore of Lake Constance at Friederichshafen.
