Slammiversary 2006 was the second annual Slammiversary professional wrestling pay-per-view event produced by Total Nonstop Action Wrestling. It took place on June 18 2006 from the iMPACT! Zone in Orlando, Florida.
Slammiversary 2006 marked the fourth anniversary of the promotion. The tagline for the event was "This is the One". In a tradition continued from Slammiversary 2005, all the referees dressed in old-school pale blue long-sleeved dress shirts, black slacks and black bowties. TNA referees usually wore short-sleeve striped shirts and black slacks. Mark "Slick" Johnson, who had as of late been dressing more casually than the other referees, wore a short-sleeved dress shirt, sneakers instead of dress shoes, and an oversized bowtie.
