John M'Clellan (also spelled M'Lellan, M'Clelland, Mackleland, Makclellan, and Macleland; 1609–1650) was a seventeenth century teacher and minister.
He took part in an unsuccessful attempt to sail to America on board the Eagle Wing in 1636.
In September 1636 he and other Scots and English puritans to the number of 140 sailed for New England in a ship called the Eagle Wing, which they had built for the purpose.
Meeting with a great storm halfway across the Atlantic, they were obliged to put back, and returned to Lochfergus, where they had embarked nearly two months before.
Returning to Scotland M'Clellan was admitted to the united parish of Kirkcudbright, Galtway and Dunrod in 1638.
