John MacDougall Hay

John MacDougall Hay (1879 – December 1919) was a Scottish novelist.

He was born and grew up in Tarbert, Argyll. He was initially a school teacher, but then became a Church of Scotland minister. He was the father of George Campbell Hay, the Scottish Gaelic poet.

He is mainly known for his novel Gillespie, set in a fictionalised version of his home town of Tarbert. It received favourable reviews when it was published in 1914, but was largely forgotten until it was re-discovered in the late 20th century. He also wrote a second novel Barnacles, and a collection of poems.

In poor health for much of his adult life, he died of tuberculosis at the age of only 39.
