Castle Rackrent is a short novel by Maria Edgeworth published in 1800, one of the few of Edgeworth's novels which her father did not “edit”. Shortly before its publication, an introduction, glossary and footnotes, written in the voice of an English narrator, were added to the original text to blunt the negative impact the Edgeworths feared the book might have on English enthusiasm for the Act of Union 1800.

Maria Edgeworth (1768 – 1849) was a prolific Anglo-Irish writer of adults' and children's literature. She was one of the first realist writers in children's literature and was a significant figure in the evolution of the novel in Europe.[2] She held advanced views, for a woman of her time, on estate management, politics and education, and corresponded with some of the leading literary and economic writers, including Sir Walter Scott and David Ricardo.
