Dean Ambrose, American wrestler
Jonathan David Good (born December 7, 1985) is an American professional wrestler currently signed to All Elite Wrestling (AEW) where he performs under the ring name Jon Moxley. He also makes additional appearances for New Japan Pro-Wrestling (NJPW), and on the independent circuit; chiefly Game Changer Wrestling (GCW), where he is the current GCW World Champion in his first reign. He became widely known for his tenure with WWE, where he performed under the ring name Dean Ambrose from 2011 to 2019.

Good made his professional wrestling debut in 2004, and competed under the Jon Moxley name in several regional promotions such as Heartland Wrestling Association (HWA), Westside Xtreme Wrestling (wXw), Full Impact Pro (FIP), Combat Zone Wrestling (CZW), and Dragon Gate USA (DGUSA). Upon signing with WWE in 2011, he was given the Dean Ambrose name and began competing in the company's developmental territories of FCW and NXT, before joining the main roster in November 2012 as a member of The Shield alongside Roman Reigns and Seth Rollins. Ambrose won the WWE United States Championship, his first championship in WWE, in May 2013; his 351-day reign became the longest United States Championship reign since the championship came under WWE's ownership. After widespread success, The Shield split in June 2014. Ambrose went on to win the WWE Championship once, the WWE Intercontinental Championship three times and the WWE Raw Tag Team Championship twice (both times with Rollins), which made him WWE's 27th Triple Crown Champion and 16th Grand Slam Champion. He also won the Money in the Bank ladder match in 2016.

Good left WWE after his contract expired in April 2019, subsequently reverting to his Jon Moxley character and debuting for AEW at their inaugural event, Double or Nothing. He also started working in NJPW and won the IWGP United States Heavyweight Championship in his debut match, becoming the first and only person to have held the WWE and IWGP United States Heavyweight Championships. He won the latter for a second time in January 2020, and became the longest reigning champion in the championship's history. He also won the AEW World Championship in February of that year, making him the first person to hold championships in AEW and NJPW simultaneously.

Long regarded as one of the best wrestlers in the world and characterized by his deranged and unstable wrestling persona, Good has also been recognized for his popularity with audiences; he won the Pro Wrestling Illustrated (PWI) award for Most Popular Wrestler of the Year in 2014 and 2015, and was named Wrestler of the Year by Sports Illustrated in 2019. He also topped the PWI 500 list of the top 500 wrestlers in the world in 2020. Outside of wrestling, he starred in the lead role of the action film 12 Rounds 3: Lockdown (2015) and as the antagonist in the sports action film Cagefighter: Worlds Collide (2020).
