Ian Michael Macdonald (born 7 March 1949), a former Australian politician, was a member of the New South Wales Legislative Council from 1988 to 2010 representing the Labor Party.
Between 2003 and 2010, Macdonald held a range of ministerial responsibilities in the Carr, Iemma, Rees, and Keneally ministries.
Macdonald, who joined the Labor Party in 1972, had his membership of the party terminated in 2013 for bringing the party into disrepute.After the Independent Commission Against Corruption found that he acted in a corrupt manner, Macdonald was charged with the offence of misconduct in public office for corruptly issuing lucrative mining licences at Doyles Creek in the Hunter Valley, found guilty by a Supreme Court jury in March 2017, and sentenced in June 2017 for a period of ten years, with a minimum custodial period of seven years.
Macdonald appealed against the verdict and, on 25 February 2019, his conviction was quashed by the NSW Court of Criminal Appeal who ordered a retrial.
He was granted bail and released from custody on the same day.
