Blair Cottrell (born November 1989) is an Australian far-right extremist and neo-Nazi.^[1][2] He is the former chairman and founding member of the United Patriots Front (UPF) and the Lads Society. He has been convicted of several charges, including stalking, arson, steroid dealing and burglary, and has spent time in prison.

Cottrell has right-wing extremist views, he has been described by numerous media outlets and Australia's former Race Discrimination Commissioner, Tim Soutphommasane, as a neo-Nazi. He has been convicted of charges of inciting hatred against communities.^[3][4][5]

Cottrell has stated a desire to see a portrait of Adolf Hitler hung in Australian classrooms and for copies of Mein Kampf to be "issued annually" to students, and has made anti-Semitic and racist comments in support of Nazism.^[6][7]

In October 2015, Blair Cottrell replaced Shermon Burgess as chairman of the United Patriots Front, and is a founding member of the Lads Society.^[6][8][9]

In September 2017, Cottrell, Neil Erikson, and Chris Shortis were found guilty by a magistrate of inciting contempt against Muslims after they had enacted and made a video of a fake beheading, to protest against the building of a mosque in Bendigo. Each was fined $2,000.^[10][5] Cottrell lodged an appeal, applying for his case to be heard in the High Court of Australia and arguing that he had been charged under an "invalid law". This was thrown out in February 2019, and he tried to have the matter heard in the Supreme Court of Victoria. The district court judge ruled that there were matters to be decided in her court, such as his intentions in making the video, before the case could proceed to a higher court, and set a date for the appeal to be heard in the county court.^[11] The county court dismissed Cottrell's appeal in December 2019. The judge also said: "even if the ends were political, the means remain vilifying. Having a political end is not a defence to the charge.“^[12]

During the COVID-19 pandemic Cottrell spread anti-vaccine misinformation.^[21][22]

In 2012, Cottrell served four months in Port Phillip Prison after being convicted of stalking his ex-girlfriend and her new partner, and of arson after attempting to burn down the man's house. In December 2013 he was fined $1,000 and sentenced to seven days in jail by a County Court judge for aggravated burglary, property damage, arson, testosterone trafficking, possessing a controlled weapon and breaching court orders.^{[23][24][25][10]}
