Wynn Hall is a 17th-century house in the old hamlet of Bodylltyn in Ruabon, Wrexham, Wales standing at the junction of the Penycae Road and Plas Bennion Road. It was built in about 1649 by William Wynn. During the English Civil War he served on the Parliamentarian side and was imprisoned at Denbigh Castle. Wynn was one of the commissioners named in the 1650 Act for Propagating the Gospel in Wales. During the 17th and 18th centuries the family was connected with the development of the nonconformist cause in the Wrexham area.
