Chimamanda Ngozi Adichie is a Nigerian writer and activist, regarded as a central figure in postcolonial feminist literature. Her works have been translated into more than fifty-five languages.

She is the author of the novels Purple Hibiscus (2003), Half of a Yellow Sun (2006), and Americanah (2013). Her other works include the book of essays We Should All Be Feminists (2014); Dear Ijeawele, or A Feminist Manifesto in Fifteen Suggestions (2017); a memoir, Notes on Grief (2021); and a children's book, Mama's Sleeping Scarf (2023).

Adichie was born and raised in Enugu. After her secondary education, she studied medicine and pharmacology for a year and a half at the University of Nigeria. At 19, she left Nigeria for the United States to study at Drexel University, and later attended Eastern Connecticut State University, Johns Hopkins University, and Yale University.

Her father's story during the Nigerian Civil War inspired her second novel, Half of a Yellow Sun. Citing Chinua Achebe and Buchi Emecheta as inspirations, Adichie's style blends Western and African influences, with a particular impact from Igbo culture. Her writing and speeches often explore themes of religion, immigration, gender, and culture.

Adichie's influential TED Talks include "The Danger of a Single Story" and "We Should All Be Feminists," the latter of which was sampled by Beyoncé and featured on a Dior T-shirt. She has received numerous accolades, including a MacArthur Fellowship in 2008 and induction into the American Academy of Arts and Sciences in 2017.
