Nancy Blackett is a fictional character in nine of the twelve juvenile novels in Arthur Ransome's Swallows and Amazons series of books. She acts as captain of the dinghy, Amazon and usually directing her friends in their various adventures. Nancy apparently has no real-world counterpart as an inspirational source for Ransome but appears to be completely the author's creation. Nancy is sometimes critically viewed as a subversive character for girl readers. The character appeared in a 1963 BBC television adaptation of Swallows and Amazons as well as in the 1974 and 2016 film adaptations of the book.
