One idiotic wrestling fan jumped the barricade following Dean Ambrose's match Tuesday night at the SmackDown taping -- and the footage of the guy getting tackled is BRUTAL!

It all went down in Providence, Rhode Island at the Dunkin Donuts Center ... when the overzealous fan was taken down in glorious fashion by security during his attempt to rush the WWE Superstar.

In the video, Ambrose calmly waits for security to boot the fan ... then continues pandering to the crowd like a boss.

Watch and enjoy -- even though the video was filmed vertically.
