Dillon Danis (born August 22, 1993)[7] is an American former submission grappler, mixed martial artist and professional boxer.

He made his MMA debut at Bellator 198 against Kyle Walker and won via a toe hold in the first round.

He was involved in a melee at UFC 229 after Khabib Nurmagomedov proceeded to throw his mouthpiece and then scaled the cage and appeared to jump towards him.

In boxing, he was scheduled to face British YouTuber KSI at MF & DAZN: X Series 004, but withdrew due to lack of preparation and coaching.

Due to his image in the media prior to the fight with Diaz, Marcelo Garcia disassociated Danis from his school.

[19] Danis hit the free agency market and aimed to get a deal with the UFC, but stated his intention to not participate in MMA again if he did not get signed.

[20][21] A month after his exit from Bellator, Danis subsequently announced his retirement from combat sports on November 15, 2023.

[26] Global Fight League announced on January 24, 2025 that Danis had signed a contract to make his return to MMA later that year.

[31] On November 18, 2022, Danis made an appearance at the press conference for MF & DAZN: X Series 003 where he confronted British YouTuber KSI.

During the broadcast on November 19, it was announced that Danis would face KSI on January 14, 2023, at Wembley Arena in London, England as the headliner to X Series 004.

[44] Danis did not comment publicly until March 11, 2019, where he told Ariel Helwani on the ESPN MMA podcast that Khabib started taunting him in the second or third round and was aggressive throughout the event.

[46][47] Danis later claimed that the bouncer and bartenders from the nightclub were at fault for the altercation, and that officers released him after approximately twenty minutes.

[48] In October 2021, Danis accused UFC veteran Jake Shields of offering him PEDs prior to the 2017 ADCC Submission Fighting World Championship.

[56] On September 1, in the buildup to his bout against Logan Paul, Danis shared the first picture of himself holding his infant son.
