Anna Montgomery Campbell (1991 – 15 March 2018), also known by her Kurdish name Hêlîn Qereçox,[a] was a British feminist, anarchist and prison abolition activist who fought with the Women's Protection Units (YPJ) in the Rojava conflict of the Syrian civil war.

According to The New York Times, she was moved by the defence of "an autonomous, mostly Kurdish region in northern Syria, known as Rojava, whose leaders advocate a secular, democratic and egalitarian politics, with equal rights for women".

[9][10] The YPJ announced:[11][12][7] Our British comrade Hêlîn Qereçox (Anna Campbell) has become the symbol of all women after resisting against fascism in Afrin to create a free world.

[13] Following the announcement of Campbell's death, her father started a campaign to recover her body, which could not be located by aid organisations until a ceasefire was in place in the area.
