John Allan Rolls, 1st Baron Llangattock, DL (19 February 1837 – 24 September 1912) was a British landowner, Conservative Party politician, socialite, local benefactor and agriculturalist.

In late October - early November 1900 the Duke and Duchess of York (later King George V and Queen Mary) stayed with Rolls at the Hendre.

He was succeeded by his eldest son, John Rolls, 2nd Baron Llangattock, who died of wounds received at the Battle of the Somme in 1916.

[9] He was a prominent member of the Anti-Vivisection Society, a position that caused some controversy as illustrated by a letter of June, 1901 published in the British Medical Journal: SIR,-I see that Lord Llangattock, who presided at the annual meeting of the Antivivisection Society on 9 May, gave credence to 'the horrible stories of what takes place in the laboratories of physiology,' denounced vivisection as 'misleading, immoral, and degrading,' and professed 'a sentiment for animals.'

Now, I recollect reading in the newspapers last autumn a description of a battue on a large scale, given by Lord Llangattock at his place in Wales, at which a phenomenal number of pheasants were shot for the recreation of Lord Llangattock and his friends, and I should like him to study this little picture of his own dealings with animals, for which he has 'a sentiment' drawn not by a vivisector, but by a man who is a keen and trustworthy observer, and who is in genuine sympathy with all sentient beings.
