Sir Ronald George Hatton, CBE FRS (6 July 1886 – 11 November 1965) was a British horticulturalist and pomologist.

[3] He went to work as a farm labourer, and in 1913 published a book, Folk of the Furrow, written under the pen name "Christopher Holdenby".

His principal achievement was the rationalisation, standardisation and classification of rootstocks for fruit trees.

His work led to the establishment first of the Malling series, and later, in collaboration with the John Innes Horticultural Institution, of the Malling-Merton rootstocks for apples.

He was made a CBE in 1934, was elected a Fellow of the Royal Society in 1944, and was knighted in 1949.
