David Williams (born August 25, 1972), better known by his ring name, David Young, is an American professional wrestler. Though he has mainly appeared with NWA Wildside and Total Nonstop Action Wrestling, Young has also competed for Ring of Honor, AAA and ZERO-ONE.

Williams was a professional wrestling fan from an early age, and announced his intention to become a wrestler to his parents at the age of five. On August 17, 1989 a seventeen-year-old Williams attended a wrestling show at which his friend was working as a security guard, and was asked to wrestle. He began training the next day with the Dalton, Georgia-based Mountain Wrestling Federation under Larry Santo, and adopted the ring name "David Young".

Young, dubbed "the Messiah of the Spinebuster", spent his early career in National Championship Wrestling as a singles wrestler before joining the team Body Count with "Heavy Metal" Ric Savage. Young and Savage feuded with Rusty Riddle and Kid Kash for the National Championship Wrestling world tag-team titles. Young stayed with NCW as it grew into NWA Wildside where Young became known as a tag team specialist, teaming with Shane Austin as "The Sex Pistols". On August 19, 1999 The Sex Pistols defeated Bart Sawyer and Terry Lawler in Loganville, Georgia for the NWA Wildside (Georgia) Tag Team Championship. On November 4, Austin was replaced by Rick Michaels, with Young and Michaels naming themselves Bad Attitude. On November 20, 1999 in Cornelia, Georgia, Young and Michaels lost the Tag Team Championships to The Road Hoggs (Joe Harley and Pan Head Nelson). Bad Attitude continued to pursue the Wildside Tag Team Championships, and on January 11, 2000 they defeated The Underdogs (Mark E. Mark and Big Eddie Cool) for the NWA Wildside Tag Team Championship, which they held until February 19, when they were defeated by The Rock 'n' Roll Express. Bad Attitude reclaimed the Tag Team Titles on June 17 in a two out of three falls match, making Young a three time NWA Wildside Tag Team Champion.

Bad Attitude set their sights on the World Tag Team Championship, and on August 15 in Tampa, Florida they defeated Curtis Thompson and Jeff Justice for the NWA World Tag Team Championship. As a result, they were stripped of the Wildside Tag Team Championship on August 19. They held the World Tag Team Championship until February 3, 2001, when they lost to Joey Matthews and Christian York in Nashville, Tennessee. Bad Attitude reclaimed the title in their home territory, Cornelia, on February 17, but soon lost them once more, losing to Dan Factor and David Flair on March 22 in Athens, Georgia. They took the title a third time the next day in Toccoa, Georgia, with what would be their final reign lasting until April 24, when they lost to The New Heavenly Bodies (Casanova Chris and Vivacious Vito) in Tampa.

Michaels and Young eventually parted ways in a somewhat acrimonious split, and Michaels went on to win the NWA Wildside (Georgia) Heavyweight Championship. During a December 22, 2001 title defense against AJ Styles, Young interfered, enabling Styles to pin Michaels and win the belt. This led to a three-way dance on March 23, 2002 at Hardcore Hell 2002, with Young eventually taking the win and becoming the Wildside Heavyweight Champion. He held the title until June 1, when he lost to Jason Cross. After Cross retired from wrestling, Adam Jacobs won the vacant title, but failed to appear for an August 3 title defence against John Phoenix. Young, a Wildside mainstay, was substituted into the match, and defeated Phoenix to become a two-time Wildside Heavyweight Championship. He held the belt until September 22, 2002 when he lost to Edward Chastaine "Iceberg".

David Young joined Total Nonstop Action Wrestling in June 2002, and wrestled a dark match against Apolo on June 19. He worked in TNA as a lower-card heel. On September 24, 2003, Young acted as the tag team partner of Simon Diamond when Diamond's usual partner, Johnny Swinger, was sidelined with appendicitis. The next week, Young assumed that he was now a member of Glenn Gilbertti's stable, the New York Connection (NYC), along with Diamond and Swinger, but Gilberti insisted that he first had to "prove himself" by defeating The Sandman. Young lost, and was subsequently beaten down by Gilberti and his clients. The following week, Young earned a spot in the group by helping them defeat the 3 Live Kru in a six-man tag match.

The stable began to fall apart, and on January 14, 2004 split into two tag teams; Gilberti and Young, and Simon and Swinger. Gilberti and Young went on to feud with the Insane Clown Posse, with Young claiming to be afraid of clowns. Young then began regularly losing his matches, with his losing streak leading Gilberti to turn on him. On August 11, Young finally broke his losing streak by pinning Gilberti in a "Final Gut Check match", then left TNA for several months. He returned on December 24, losing to Abyss. Young appeared sporadically with TNA for several months, and on July 17 at No Surrender 2005 he reforged his alliance with Simon Diamond, who offered to make him "a diamond in the rough". On February 22, 2007, TNA released David Young.

At Slammiversary, on June 19, 2022, Young made an unannounced appearance as a participant in the Reverse Battle Royal, which he failed to win as he was eliminated by Johnny Swinger.
