Maureen Anne Lyster (born 10 September 1943) is an Australian politician.
She was a Labor Party member of the Victorian Legislative Council from 1985 to 1992, representing Chelsea Province.
In 1989, she was promoted to Minister for Local Government after the National Party blocked a Labor attempt to increase the number of ministers that could be constitutionally appointed from the Legislative Assembly, resulting in her appointment instead of right faction candidate and MLA Barry Rowe.
[2][3] In September that year, she was subject to a successful no-confidence motion in parliament, which would not happen to a state minister again until 2009.
[1] Lyster held a number of roles in the health sector after leaving politics, including as CEO of Riding for the Disabled (1993), CEO of the Alzheimers' Association of Victoria (1993–1996), CEO of Aged Care Australia (1996–2000), and a stint as a board member of Mercy Health and Aged Care thereafter.
