Nathan Joel Marquardt (born April 20, 1979) is an American mixed martial artist. He is a three-time Middleweight Pancrase Champion and former UFC middleweight title contender.

As a middleweight (he now fights at welterweight), Marquardt was ranked the #4 best middleweight in the world by Sherdog and the #3 middleweight fighter in the world by MMAWeekly. He runs the High Altitude Martial Arts Academy in Aurora, Colorado.

Marquardt began his professional mixed martial arts career in 1999, amassing victories in various promotions before entering the Bas Rutten Invitational 4 tournament, which was organized in such a manner that the tournament winner was to be offered a contract with the Ultimate Fighting Championship. Despite winning the tournament, Marquardt was offered no such contract. Instead, he signed with Japan's Pancrase organization, which had fostered such fighters as Ken Shamrock and Bas Rutten. In his first Pancrase fight, Marquardt lost via submission to Genki Sudo.

Invited back to Pancrase for a middleweight elimination tournament, Marquardt defeated Daiju Takase, Kiuma Kunioku, and Shonie Carter to become the first middleweight King of Pancrase. Marquardt defended this title twice before being defeated by Kunioku in December 2001. A final encounter between the two fighters in December 2002 saw Marquardt defeat Kunioku once again to recapture the King of Pancrase championship, which he held for nearly a year.^{[citation needed]}

White has a background as an aerobics instructor. In 1992, White established Dana White Enterprises in Las Vegas. He conducted aerobics classes at three gyms in the Las Vegas area and began managing MMA fighters Tito Ortiz and Chuck Liddell.

While working as a manager, White learned that Semaphore Entertainment Group, the parent company of the UFC, was looking for a buyer for the UFC. White contacted childhood friend Lorenzo Fertitta, an executive at Station Casinos, and a former commissioner of the Nevada State Athletic Commission. Within a month, Lorenzo and his older brother Frank bought the UFC, with White installed as its president. White currently owns about 9% of Zuffa, LLC, the entity the Fertitta brothers created to own and manage the UFC.
