Tyga is mourning the death of his friend and bodyguard, who was killed in a freak accident on an L.A. freeway ... TMZ has learned.

Arlester Henderson -- known as Punch to Tyga and his crew -- was at the wheel early Wednesday morning when he got into a collision with another vehicle on the 10 freeway.

Cops say Punch got out of his SUV to check on people in the other car. That's when he was struck and killed by a passing car. 

Tyga's rep tells TMZ the rapper is "devastated, shocked and heartbroken." Henderson was 29.
