Frågan om det finns liv på Mars har varit föremål för vetenskaplig diskussion under de senaste århundradena. Rymdsonder har från 1960-talet och framåt visat att det inte finns något intelligent liv på Mars. Det är däremot fortfarande inte klarlagt om det finns eller har funnits mikrobiologiskt liv på planeten.
Science fiction
Inom science fiction har intelligenta marsianer varit vanligt förekommande, framförallt innan det blev klarlagt att det inte finns något intelligent liv på planeten. Bland böcker och filmer med marsianer finns bland annat H.G. Wells roman Världarnas krig (1898), den danska stumfilmen Himmelsskeppet, (1918) den sovjetiska stumfilmen Aelita (1924) och Tim Burtons film Mars Attacks! (1996).
Kultur
David Bowie gav 1971 ut albumet Hunky Dory, där låten Life on Mars? fanns med. Låten röstades fram som en av 1900-talets bästa låtar.

Mars Hubble.jpg
NASA's Hubble Space Telescope took the picture of Mars on June 26, 2001, when Mars was approximately 68 million kilometers (43 million miles) from Earth — the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 16 kilometers (10 miles) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap (top of image), and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere (lower right).
