Colin John (Col) Miller (28 April 1924 – 4 November 2016) was an Australian politician.
He was a member of the Queensland Legislative Assembly from 1966 to 1986, representing the electorate of Ithaca as a Liberal (1966–1984) and as an independent (1984–1986).
In World War II he was a corporal in the Australian Imperial Force and was assigned to the 2/3 Field Park from 1943 to 1946.
Miller, for the Liberal Party, held the seat of Ithaca in the Queensland Legislative Assembly from in 1966 until his retirement from politics in 1986.
Although it had been rumoured that he would join former colleagues Don Lane and Brian Austin in defecting to the National Party, this did not occur and he continued to sit as an independent.
