Gareth Richard Vaughan Jones (13 August 1905 – 12 August 1935) was a Welsh journalist who in March 1933 first reported in the Western world, without equivocation and under his own name, the existence of the Soviet famine of 1930–1933, including the Holodomor and the Asharshylyk.

Jones had reported anonymously in The Times in 1931 on starvation in both Soviet Russia and Soviet Ukraine. After his third visit to the Soviet Union, he issued a press release under his own name in Berlin on 29 March 1933 describing the widespread famine in detail. Reports by Malcolm Muggeridge, writing in 1933 as an anonymous correspondent, appeared contemporaneously in the Manchester Guardian; his first anonymous article specifying famine in the Soviet Union was published on 25 March 1933.

After being banned from re-entering the Soviet Union, Jones journeyed to the Far East to report on the Japanese invasion of Manchuria. Ignoring warnings from the British Embassy of their presence, he was kidnapped by Chinese bandits and murdered in 1935 while investigating in Japanese-occupied Inner Mongolia; his murder is suspected by some to be the work of the Soviet secret police, the NKVD. Upon his death, former British prime minister David Lloyd George said, "He had a passion for finding out what was happening in foreign lands wherever there was trouble, and in pursuit of his investigations he shrank from no risk. … Nothing escaped his observation, and he allowed no obstacle to turn from his course when he thought that there was some fact, which he could obtain. He had the almost unfailing knack of getting at things that mattered."

Born in Barry, Glamorgan, Jones attended Barry County School, where his father, Major Edgar Jones, was headmaster until around 1933. His mother, Annie Gwen Jones, had worked in Russia as a tutor to the children of Arthur Hughes, son of Welsh steel industrialist John Hughes, who founded the town of Hughesovka (modern-day Donetsk) in today's eastern Ukraine.

Jones graduated from the University College of Wales, Aberystwyth in 1926 with a first-class honours degree in French. He also studied at the University of Strasbourg and at Trinity College, Cambridge, from which he graduated in 1929 with another first in French, German, and Russian. After his death, one of his tutors, Hugh Fraser Stewart, wrote in The Times that Jones had been an "extraordinary linguist". At Cambridge he was active in the Cambridge University League of Nations Union, serving as its assistant secretary.

After graduating, Jones taught languages briefly at Cambridge, and then in January 1930 was hired as Foreign Affairs Adviser to the British MP and former prime minister David Lloyd George, thanks to an introduction by Thomas Jones. The post involved preparing notes and briefings Lloyd George could use in debates, articles, and speeches, and also included some travel abroad.

In 1929, Jones became a professional freelance reporter, and by 1930 he was submitting articles to a variety of newspapers and journals.

In late January and some of February 1933, Jones was in Germany covering the accession to power of the Nazi Party, and he was in Leipzig on the day Adolf Hitler was appointed Chancellor. Some three weeks later, on 23 February in the Richthofen, "the fastest and most powerful three-motored aeroplane in Germany", Jones, along with Sefton Delmer, became the first foreign journalists, after he became Chancellor, to fly with Hitler. They accompanied Hitler and Joseph Goebbels to Frankfurt where Jones reported for the Western Mail on the new Chancellor's tumultuous acclamation in that city. He wrote that if the Richthofen had crashed the history of Europe would be changed.
