Lady of the Glen: A Novel of 17th-Century Scotland and the Massacre of Glencoe is a 1996 historical fiction novel by American author Jennifer Roberson. It is a re-telling of the 1692 Massacre of Glencoe, and focuses on the romance between Catriona of Clan Campbell and Alasdair Og MacDonald of Clan Donald, each from rival clans. Roberson was inspired to write the novel after learning of the massacre in a British history class, and waited 25 years until she felt ready to tell it.
