John Gallda MacDougall (died 1371–1377), also known as John MacDougall, and John Macdougall, and in Gaelic as Eoin MacDubhghaill, Eoin Gallda MacDubhghaill, Eòin Gallda MacDubhghaill, and Eóin Gallda Mac Dubhghaill, was a fourteenth-century Scottish magnate. He was a grandson of John MacDougall, Lord of Argyll, a man who had been forced from Scotland into exile in the first third of the century. It was under John Gallda that the MacDougall leadership made its resurgence in Scotland after generations of English exile.
