Lucía Puenzo (born 28 November 1976, Buenos Aires) is an Argentine author, screenwriter and film director.

She is the daughter of the Oscar-winning film director, producer, and screenplay writer, Luis Puenzo.

In the work that she creates, writes and directs, such as XXY and The German Doctor, she focuses on the question of medically modified bodies.

Although her work features sound, she makes an effort to not solely rely on dialogue if a scene can be told with a look.

[3] On top of directing and screenwriting, Puenzo also has written several novels including El Niño Pez and Nueve Minutos.
