The Book of the Dean of Lismore is a Scottish manuscript, compiled in eastern Perthshire in the first half of the 16th century. The chief compiler, after whom it is named, was James MacGregor, vicar of Fortingall and titular Dean of Lismore Cathedral, although there are other probable scribes, including his brother Donnchadh and William Drummond, curate of Fortingall. It is unrelated to the similarly named Book of Lismore, an Irish manuscript from the early 15th century.
