The World Wrestling Entertainment (WWE) Cruiserweight Championship was a professional wrestling championship in World Wrestling Entertainment and was originally a World Championship Wrestling (WCW) title. It was challenged by cruiserweights at a maximum weight of 215 lbs. During its tenure in WWE, it was exclusive to the SmackDown! brand.

The WWE Cruiserweight Championship is recognized as formerly being the WCW Light Heavyweight Championship; a title that was considered separate from the WCW Cruiserweight Championship at the time by WCW. Following the Light Heavyweight title's introduction in 1991, a tournament was held to determine the inaugural champion. On October 27, Brian Pillman defeated Richard Morton in the tournament final to win the title. However, when Brad Armstrong was forced to relinquish the title due to injury on September 2, 1992, it became inactive. Then, on March 20, 1996, Shinjiro Otani defeated The Pegasus Kid (Chris Benoit) in a decision match to win what then became known as the WCW Cruiserweight Championship.

London made his debut in WWE in late 2003 and immediately began teaming with fellow cruiserweight Brian Kendrick, known as Spanky at the time.
