Name given to native inhabitants of the planet Mars. There have been many fictional depictions of Martians in the past, including the famous invaders from H. G. Wells' novel The War of the Worlds, and also many people who have believed in the existence of real Martians. At this point in time it is generally accepted that Mars has no large-scale native life, and even the presence of bacteria-scale life is speculative at best.
If Mars is one day colonized by humans, the generations descended from the settlers will also be called Martians.
