Jasper Douglas Pyne (1847 – 14 November 1888) was an Irish nationalist politician from County Waterford who served as a Member of Parliament (MP) from 1885 until his unexplained death. Pyne was the fourth child of the Reverend William Masters Pyne and his wife Marian. Rev W. M. Pyne came from Ballyvolane near Cork but he was the Rector of St Mary's Church in Oxted, Surrey, from 1828 to 1869, a remarkable tenure of 41 years. The Pyne family lived in the Rectory (now called Oxted Place) until the Rev W. M. Pyne inherited Ballyvolane House on his father's death.
