Zahra "Ziba" Kazemi-Ahmadabadi (1948 – July 11, 2003) was an Iranian-Canadianfreelance photographer, who according to the medical examiner was raped, tortured and killed by Iranian officials following her arrest in Iran

Her death was the first time an Iranian's death in custody attracted major international attention. Because of her joint citizenship and the circumstances of her death, she has since become an international cause célèbre. In November 2003, Canadian Journalists for Free Expression honoured Kazemi with the Tara Singh Hayer Memorial Award in recognition of her courage in defending the right to free expression
