Ester Krumbachová (12 November 1923 – 13 January 1996) was a Czech screenwriter, costume designer, stage designer, author and director.
She is known for her contributions to Czech New Wave cinema in the 1960s, including collaborations with directors Vera Chytilová and Jan Nemec.
In 2017, a private archive of Krumbachová's artwork, photography, documents, and clothes was made accessible by curators Edith Jerábková and Zuzana Blochová.
Krumbachová has since been the subject of retrospective exhibitions at TRANZITDISPLAY, Prague (2017) and the CCA: Centre for Contemporary Arts, Glasgow (2018).
