Conor McGregor appeared on The Tonight Show Starring Jimmy Fallon on June 16, 2026 ; he had also been on the show previously in March 2019 during a special Irish pub segment in Dublin.

Quick scoop: the 2026 appearance

  • Date: June 16, 2026 (episode aired that night).
  • Context: McGregor was part of a New York media tour promoting his return to the UFC at UFC 329.
  • Backlash: The interview sparked significant criticism online because it did not address the 2026 U.S. civil court ruling in the Nikita Hand sexual assault case, with some commentators calling the appearance “the lowest blow” and accusing Fallon of being cowardly for not mentioning the ruling.

Why this appearance is being talked about now

The 2026 talk is a current trending topic on forums and social media, with:

  • Actresses like Christina Ricci posting on Instagram that Fallon should be “ashamed” for hosting McGregor.
  • Comedian Kathy Griffin claiming she was “banned” from The Tonight Show and using McGregor’s appearance as an example of Fallon’s “controversial” guest choices.
  • Writings and posts calling the appearance a moral failure because the interview avoided the civil case entirely.

This has turned the date of the appearance (“when was Conor McGregor on Jimmy Fallon”) into a recurring forum discussion point, especially in posts comparing late-night hosts’ choices around controversial figures.

Earlier appearance: 2019 Dublin segment

McGregor also appeared on Jimmy Fallon’s show in March 2019 , but not in the usual studio setting:

  • Fallon traveled to Dublin and interviewed McGregor at Paddy Reilly’s Music Bar.
  • They discussed McGregor’s Proper No. Twelve whiskey, his past as a plumber, and his charitable work.

That 2019 segment is often remembered as a more low-key, “funny story”-type moment compared to the heated controversy around the 2026 interview.

Summary timeline

If you’re tracking the “latest news” or forum discussion about this, most of the buzz in June–July 2026 is about the 2026 appearance and the criticism it generated, not the 2019 pub chat.
