Josef Mai (1887-1982) was a German First World War fighter ace credited with 30 confirmed and 15 unconfirmed aerial victories while flying combat for Jagdstaffel 5.
While flying for them as a sergeant pilot, he shot down enemy aircraft from August 1917 until war's end.
Mai was noted as being one of a trio of high-scoring sergeant pilots called the Golden Triumvirate whose collective victories for Jagdstaffel 5 totaled more than 100; the other two aces were Otto Könnecke and Fritz Rumey.
