Corbynmania was the enthusiastic support for Jeremy Corbyn.
Initially viewed as a token candidate for the left-wing of the party and not expected to win, Corbyn's authentic, informal style and radical policies appealed to many of the young new members who had joined after the membership fee had been reduced to £3.
Hundreds of supporters turned out to hear him speak at the hustings across the nation and their enthusiastic reception and support for him was dubbed "Corbynmania" by the press.

Jonathan Dean characterised Corbymania as a political fandom, comparable with the enthusiastic followings of popular media stars and other modern politicians such as Bernie Sanders and Justin Trudeau.
  Specific features included use of the #jezwecan hashtag, attendance at rallies and the posting of pictures such as selfies on social media.
 Artistic, merchandising and other activity consolidated and spread this fannish enthusiasm.
 This included a  “Jeremy Corbyn for Prime Minister” (JC4PM) tour by celebrities such as Charlotte Church, Jeremy Hardy, and  Maxine Peake; a Corbyn superhero comic book; mash-ups and videos.
 Corbyn's personal qualities were earnest and modest and these inspired warm emotions such as devotion and loyalty.
 These were seen as cultish by critics such as Margaret Beckett who said in 2016 that the Labour Party had been turned into the "Jeremy Corbyn Fan Club".

A chant of "Oh, Jeremy Corbyn" was adopted as an anthem or chorus by his supporters.
 Sung in the style of a football chant to the tune of a riff from "Seven Nation Army" by The White Stripes, it attracted especial attention at the Glastonbury Festival of 2017, where Corbyn appeared and spoke to the crowds.

Labour's weaker than expected performance in the 2018 United Kingdom local elections led to suggestions that Corbynmania had peaked.
Following Labour's considerable losses at the 2019 United Kingdom general election, Corbyn stepped down as Leader.
