Josephine Hamilton is a former subpostmaster and a campaigner for justice for victims of the British Post Office scandal. She ran a village post office in Hampshire from 2001 until 2006, when she was suspended and then wrongly prosecuted for shortfalls caused by the Post Office faulty accounting software, Horizon. She was convicted of false accounting, received a supervision order and had to pay the Post Office £36,000 although it was money she did not owe.
