Jang Eun-Jin (born 1976) is a female South Korean writer.

Jang attended Cheonam National University in Gwangju from which she graduated with a degree in Geography. She has published four novels and a collection of short stories and has won three literary prizes in total The Chonnam Ilbo New Short Story Award in 2002, the Joongang Ilbo New Writers Contest in 2004, and the 14th annual Munhakdongne Award in 2009.

Jang has had one book translated into English, No One Writes Back (Translated by Jung Yewon), which The Guardian reviewed as, “An extraordinarily rich and moving novel about a young man's journey through South Korea with his dog” Her subject is communication, or its absence, and the book is written as a picaresque. It is the story of a young man, MP3 player and blind dog, and their three-year goal-less journey, and who they meet on that journey. The fellow travelers are anonymous, earning numbers in replacement for names, but the narrator nonetheless writes them letters, in the hope that someday a letter will come back.
