The real world inspiration for the Academy Award nominated movie "127 Hours" was arrested Saturday night in Denver on suspicion of domestic violence ... TMZ has learned.


Aron Ralston -- the man who made headlines in '03 after he ACTUALLY amputated his own forearm with a pocket knife when a boulder dislodged and trapped him inside a Utah canyon -- faces one count of assault and one count of "wrongs to minors" ... according to reports.


The movie based on his best-selling book was nominated for 6 Oscars -- including a Best Actor nom for James Franco who played Ralston.


Aron is currently being held in Denver County jail with no bail and is scheduled to appear in front of a judge tomorrow.
