UFC 5: The Return of the Beast was a mixed martial arts event held by the Ultimate Fighting Championship on April 7, 1995, at the Independence Arena in Charlotte, North Carolina. The event was seen live on pay per view in the United States, and later released on home video.

UFC 5 used an eight-man tournament format, with the winner receiving $50,000. The event also featured the first ever UFC Superfight, as well as two alternate fights, which were not shown on the live pay-per-view broadcast. The tournament had no weight classes, or weight limits. The fights had to end by knockout or submission; therefore no judges were used.

UFC 5 also introduced the first 'Superfight', which was the first non-tournament singles match in UFC history. The Superfight match was the main attraction, and the winner of this fight would become the reigning UFC Champion. It consisted of rivals Royce Gracie and Ken Shamrock facing off in the most anticipated match in UFC history to that date. Up to this point, Ken Shamrock's only defeat was to Royce Gracie in UFC 1.

Kenneth Wayne Shamrock (born Kenneth Wayne Kilpatrick; February 11, 1964) is an American mixed martial artist, UFC Hall of Famer and professional wrestler. Shamrock emerged as one of the biggest stars in the history of mixed martial arts, headlining over 15 main events and co-main events in the Ultimate Fighting Championship and Pride Fighting Championships during the course of his career and set numerous pay per view records with his drawing power. Shamrock is widely considered to be a legendary figure and icon in the sport of mixed martial arts. Shamrock was named The World's Most Dangerous Man by ABC News in a special entitled "The World's Most Dangerous Things" in the early part of his UFC career, a moniker which has become synonymous as his nickname.

Shamrock became known early on in the UFC for his rivalry with Royce Gracie. After fighting to a draw with Gracie in the inaugural Superfight, he became the first UFC Superfight Champion after defeating Dan Severn at UFC 6; the title was eventually renamed the UFC Heavyweight Championship when weight categories were introduced to the UFC. He was also the first foreign MMA Champion in Japan, winning the title of King of Pancrase. During his reign as the UFC Superfight Champion, he was widely considered the #1 mixed martial artist in the world. Shamrock was also ranked by Inside MMA as one of the top 10 greatest mixed martial arts fighters of all time.
