Alex Hearn is a prominent British activist and the director of Labour Against Antisemitism (LAAS), an organization focused on addressing antisemitism within the Labour Party and wider political discourse. Hearn has been a vocal advocate against antisemitism, often challenging the narratives that he believes fuel prejudice against the Jewish People. His work includes rebutting claims of Israel being labeled an apartheid state, and he is known for his critiques of figures and institutions that he believes undermine the fight against antisemitism.

Hearn's advocacy efforts have included confronting anti-Israel and antisemitic rhetoric in both political and public arenas, often leading to significant debate and backlash, particularly around high-profile figures like former Labour leader Jeremy Corbyn and others who have been associated with antisemitic controversies. His work regularly appears in media outlets such as The Jewish Chronicle and Jewish News, where he writes extensively on issues related to antisemitism, the Israel-Palestinian Conflict, and media bias.
