William Arthur Dunkerley (12 November 1852 – 23 January 1941) was an English journalist, novelist, and poet. Born in Manchester, England, Dunkerley spent some time in the United States after his marriage before settling in Ealing, West London. There, he was active in the community as a deacon and teacher at the Ealing Congregational Church during the 1880s. In 1922, he moved to Worthing, Sussex, where he served as the town's mayor.

Dunkerley was a versatile writer, publishing under his own name as well as the pseudonyms John Oxenham and Julian Ross. As John Oxenham, he was known for his poetry, hymn-writing, and novels. His collection "Bees in Amber: A Little Book of Thoughtful Verse" (1913) became a bestseller. He is also remembered for his hymn "In Christ there is no east or west," composed in 1908 and included in numerous Christian hymnals. His poem "Greatheart" is another notable work.

In journalism, Dunkerley used the pseudonym Julian Ross. He co-founded "The Idler," a monthly magazine, with Robert Barr in 1892. Dunkerley's novel "A Mystery of the Underground" (1897) is recognized as an early crime story set on the London Underground, notable for its realistic depiction which reportedly affected passenger numbers during its serialization.

Dunkerley had a family of six children, including his eldest daughter Elsie Jeanette, who became a well-known children's writer, and his son Roderic, who was a Congregational minister and Christian writer.
