TMZ Sports has obtained former Olympic ski star Bode Miller's mug shot ... and the ex-athlete's expression is giving legal wipeout.

We broke the story ... Miller was charged with two misdemeanors stemming from an incident in Idaho on June 6 -- possession of a controlled substance and possession of paraphernalia.

48-year-old Miller's booking sheet has him listed at 6'2", 200 pounds ... and noted a scar in the shape of a No. 7 on his palm.
