Frederick Brocklehurst (1866 – 1926) was a British political activist best known for his early involvement in the socialist movement. Brocklehurst began working in a silk mill when only ten years old. He subsequently worked at the presses of the Manchester Courier newspaper, before obtaining a scholarship to Queen's College, Cambridge, where he graduated in law. An activist in the Labour Church, he returned to Manchester after John Trevor passed the church leadership to him. He was a founder member of the Independent Labour Party (ILP), and in 1894 was elected to its national council.
