Jack Jones CBE (24 November 1884 – 7 May 1970) was a Welsh miner, Trade Union official, politician, novelist and playwright.

In 1901 at the age of 17 he joined the army and was posted to South Africa with his regiment the Militia Battalion of the Welch.

After suffering shrapnel wounds he was invalided home and appointed as recruiting officer for Merthyr Tydfil.

He attended a convention in Manchester on behalf of his local miners lodge with the purpose of establishing the party; at this meeting he was chosen to be Corresponding Secretary for the South Wales Region.

He stood as Liberal candidate for Neath at the 1929 General Election and polled nearly 30%; He did not stand for parliament again.

During his 20s Jack Jones began to educate himself and develop his love of the theatre and writing, often taking part in local dramatic productions.

In 1926 he successfully entered a short play he had written entitled Dad's Double into a competition in Manchester.

By 1939, he had written the novels Rhondda Roundabout (1934), and Bidden to the Feast (1938), a play, Land of my Fathers (1937), and his first autobiography, Unfinished Journey (1937).

After the war he wrote two volumes of autobiography, Me and Mine (1946) and Give Me Back My Heart (1950), three novels, Off to Philadelphia in the Morning (1947) made into a BBC drama of the same name in 1978, Some Trust in Chariots (1948), and River Out of Eden (1951), and a play Transatlantic Episode (1947).

His later works, Lily of the Valley and Lucky Year (1952), Time and the Business (1953), Choral Symphony (1955) and Come, Night; End, Day (1956) were less well received.

Until his death in May 1970 he continued writing; these works remained unpublished, including a biographical novel, A Burnt Offering, based on the life of Dr William Price (1800–1893), Llantrisant, pioneer of cremation.
