Charlotte Luise Antoinette von Schiller (née von Lengefeld; 22 November 1766 – 9 July 1826) was the wife of German poet Friedrich Schiller.

 Though never a published author during her lifetime, Lengefeld was a writer her entire life. Her letters to her husband, her sister, Stein, Goethe, and others have been published in multiple editions.[5] She has also been identified as the author of several works found among her husband's papers and posthumously included in collected editions alongside his work, notably the novel Die heimliche Heirat (The Secret Marriage).[6] Along with other women in the Goethe-Schiller circle, Lengefeld has been receiving increased critical attention; critic Gaby Pailer wrote the first full-length scholarly book on her life and work, published in 2009
