Jonathan David Good (born December 7, 1985) is an American professional wrestler and actor currently signed to All Elite Wrestling (AEW), where he performs under the ring name Jon Moxley. He also makes appearances in New Japan Pro-Wrestling (NJPW), where he is the current IWGP United States Champion in his first reign. He is well known for his time with WWE, where he performed as Dean Ambrose from 2011 to 2019.
Good began his professional wrestling career in 2004 on the American independent circuit as Jon Moxley, working for various regional promotions including Full Impact Pro (FIP), Combat Zone Wrestling (CZW), and Dragon Gate USA (DGUSA). He won several top promotional championships, including the FIP World Heavyweight Championship once, the HWA Heavyweight Championship once, and the CZW World Heavyweight Championship twice.
After signing with WWE in 2010 under the ring name Dean Ambrose, Good competed in their developmental territories Florida Championship Wrestling and NXT until 2012. He joined the main roster in November 2012 as a member of The Shield with Roman Reigns and Seth Rollins. Ambrose won his first championship in WWE while in the group, the United States Championship, with his 351-day reign being the longest under the WWE banner. Following The Shield's breakup, Ambrose went on to become a one-time WWE Champion, a three-time Intercontinental Champion, and a two-time Raw Tag Team Champion (with Rollins). He was also the 2016 Money in the Bank ladder match winner. Upon winning the Raw Tag Team Championship in August 2017, Ambrose became the 27th Triple Crown Champion and the 16th Grand Slam Champion.
Following his departure from WWE, Good made an unannounced appearance at AEW's premiere event, AEW Double or Nothing, reverting back to his Jon Moxley moniker. He also started working in NJPW shortly after his WWE exit and won the IWGP United States Championship in his NJPW debut, becoming the first and only wrestler to have held the WWE and IWGP United States championships.
Outside of wrestling, Good made his acting debut in the 2015 film 12 Rounds 3: Lockdown.
