Combat Zone Wrestling's Best of the Best is a professional wrestling tournament and supershow held in the CZW promotion. The annual Best of The Best was originally a junior heavyweight tournament, which in 2005 was repurposed as an all weight tournament.

The first four tournaments saw 12 men first compete in elimination style 3-way matches in the first round before then single elimination matches until a winner was determined. During the 2005 tournament, which was held on May 14, 2005, the winner was determined by all single elimination matches. The original tournament structure returned in 2006, but saw the last four men face off in one match to determine the winner.
