UFC 64: Unstoppable was a mixed martial arts event held by the Ultimate Fighting Championship on Saturday, October 14, 2006. The event took place at the Mandalay Bay Events Center, on the Las Vegas Strip in Nevada and was broadcast live on pay-per-view in the United States and Canada.
The card also featured a UFC Lightweight Championship bout between The Ultimate Fighter alumnus Kenny Florian and longtime UFC veteran Sean Sherk. It was the first Lightweight Championship bout since UFC 41 in 2003, when B.J. Penn and Caol Uno fought to a draw.
A planned match between Keith Jardine and Mike Nickels was cancelled a day before the event when Nickels reaggravated a previous back injury sustained during training. A replacement could not be found on short notice.
