Ffynone (Welsh: Ffynnonau) is a mansion and estate near Boncath, Pembrokeshire, Wales, in the parish of Manordeifi.

The name predates the present house, and its Welsh name Ffynnonau, meaning "Wells", reflects the existence of a number of springs in the vicinity.

He had no son and left the estate to his daughter Aline Margaret, who had married Captain Cecil John Herbert Spence-Jones, son of the Dean of Gloucester, in 1908; the marriage was a notable occasion, reported in great detail, an occasion for local celebration, despite there being no guests at the wedding and no reception, owing to the bride's mother's state of health.

[5] The asking price for the house and 34 acres (14 ha) was reduced in July 2021 to £1.8 million and the property was subsequently sold for an undisclosed sum.

[4] John Nash was commissioned to design the house in the early 1790s; construction work began in 1794 and was completed by 1799.

60,000 trees were sourced from John Mackie, a Norwich nursery man, and hundreds of tons of topsoil were brought in.
