Kevin Carroll is a British far-right activist born in 1969, best known as the uncle of Tommy Robinson (real name Stephen Yaxley-Lennon) and a co-founder of the English Defence League (EDL). He served as the EDL's deputy leader and operational number two, handling organizational aspects, logistics, street demonstrations, and anti-Islam protests during the group's peak in the late 2000s and early 2010s. Carroll's involvement stemmed from his Luton roots, where he grew up in a working-class environment and became radicalized against what he perceived as Islamist extremism following events like the 2005 London bombings. He has been criticized for promoting Islamophobic rhetoric and associating with violent protests, with allegations of inciting racial hatred leveled against him and the EDL.

Carroll's activism extended beyond the EDL, which declined around 2013 amid internal splits and legal pressures. He later joined or supported groups like the British National Party (BNP) and Pegida UK, continuing to organize anti-immigration rallies. His close familial and ideological ties to Tommy Robinson have kept him in the far-right orbit, though he has maintained a lower public profile in recent years. Carroll has faced multiple arrests related to public order offenses during demonstrations, including a 2010 conviction for using threatening behavior at an EDL rally, resulting in a fine. Controversies surrounding him include accusations of thuggery and links to football hooliganism, with critics condemning his role in fostering division in British society.

Despite the EDL's collapse, Carroll remains a figure in networks of influence within the UK's far-right scene, influencing grassroots mobilization against multiculturalism. His personal life details are sparse, but he is known to have worked in manual labor jobs before dedicating himself to activism. Allegations of financial impropriety within the EDL, such as misuse of donations, have been raised but not substantiated against him personally.
