Cowan Bridge School refers to the Clergy Daughters' School, a school mainly for the daughters of middle class clergy founded in the 1820s. It was first located in the village of Cowan Bridge in the English county of Lancashire, where it was attended by the Brontë sisters. Two of the sisters, Maria and Elizabeth died from tuberculosis in the aftermath of a typhoid outbreak at the school. In the 1830s the school moved to Casterton, a few miles away, where it was amalgamated with another girls' school. The institution survived to the twenty-first century as Casterton School.
