Parsonage Colliery was a coal mine operating on the Lancashire Coalfield in Leigh, then in the historic county of Lancashire, England. The colliery, close to the centre of Leigh and the Bolton and Leigh Railway was sunk between 1913 and 1920 by the Wigan Coal and Iron Company and the first coal was wound to the surface in 1921. For many years its shafts to the Arley mine were the deepest in the country. The pit was close to the town centre and large pillars of coal were left under the parish church and the town's large cotton mills.
