John Gregorson Campbell (1836 – 22 November 1891) was a Scottish folklorist and Free Church minister at the Tiree and Coll parishes in Argyll, Scotland. An avid collector of traditional stories, he became Secretary to the Ossianic Society of Glasgow University in the mid-1850s. Ill health had prevented him taking up employment as a Minister when he was initially approved to preach by the Presbytery of Glasgow in 1858 and later after he was appointed to Tiree by the Duke of Argyll in 1861, parishioners objected to his manner of preaching.
Several of the anecdotes he amassed were published in magazines and, just before his death, work began on collating the first of four compendiums of the tales; three were published a few years after his death. He was fluent in several languages, including Scottish Gaelic, and transcribed the legends precisely as dictated by the narrators.
