Justin Bieber tempted fate at an exclusive resort in Barbados on Wednesday -- because for some terrifying reason ... the 16-year-old singer decided to throw himself off an enormous cliff.

Okay, so the cliff was barely 10 feet above the water -- but still ... pretty bad ass.

Though it doesn't change the fact that the Biebster seriously needs some boogie-boarding lessons.
