Marxism Festival 2026 returns to London from Thursday 2 to Sunday 5 July for four days of ideas, debate, culture and resistance.

Organised by the Socialist Workers Party, Marxism Festival is Britain’s biggest left wing festival, drawing thousands of people from across the UK and around the world.

Across the weekend take part in mass rallies addressing the big political questions of our time, alongside hundreds of meetings and workshops digging into history, theory and strategy. Expect sharp debates, meetings on key Marxist theory, film screenings, live music and cultural events.

Whether you’re new to socialist ideas or a long-time activist, Marxism Festival offers a welcoming space to learn, argue and organise. In a world marked by war, racism, climate crisis and inequality, we need socialist strategy and collective action more than ever.

Join us in London this July to meet thousands of others who refuse to accept the world as it is — and who are determined to fight for something better.
Secure your ticket now and be part of the biggest gathering of the left in Britain.
