Robert William Griffiths (May 28, 1896 – January 29, 1962) was a British farmer and businessman whose principal interests lay in dairy farm production in Wales.

He was descended in an unbroken male line from Brochwel Ysgithrog through the Princes of Powys, Elisedd ap Cyngen and Ieuan, the older brother of Sir Gruffudd Vychan.

In the 1950s he bought Woodlands and then the 2,000-acre (8.1 km2) Walcot Estate near Lydbury North from the Earl of Powis, which had come into his family when Robert Clive purchased it on his return from India in 1760.

Griffiths built up his prize winning Montgomery Herd of tubercular tested pedigree Friesian cows at Woodlands by introducing bulls from as far away as the Netherlands and Canada.

In 1961 he won the Royal Welsh Agricultural Society's coveted Sir Bryner Jones Memorial Award for an exceptional contribution to dairy farming in Wales.

[5] In recognition of his achievements as a farmer and businessman he was appointed High Sheriff of Montgomeryshire in 1953, and was responsible for events in the county relating to the coronation of Queen Elizabeth II.
