Joseph Fleming (6 January 1811 – 23 September 1891) was an Australian born pastoralist and politician who was a Member of the Queensland Legislative Assembly.

[3][4] Fleming was very close to his uncle, Thomas Simpson Hall, they being of similar age and having married sisters of the same McGinnis family.

[5] In the mid-1830s, Hall with the help of Fleming, expanded his family's pastoral assets by appropriating large segments of land along the upper Namoi River at Cuerindi and Mundowey, near the modern day town of Manilla.

Fleming left his brother John in charge of the run, who became well known for conducting armed raids against "the blacks", and was the leader of the gang that, in 1838, perpetrated the Myall Creek massacre.

John was able to avoid arrest by fleeing the region but one of Fleming's 'Mungie Bundie' stockmen who participated in the massacre, Edward Foley, was later hanged for his involvement in the crime.

In 1839, he led a group in the capture of bushranger "Gentleman Dick" and his gang, who had attempted to shoot Fleming and rob his 'Mungie Bundie' station.

[8] He soon after returned to the Hawkesbury region where he was appointed to the role of district chief constable of the police force even though his brother was still a high-profile wanted felon.

[10] At Talavera, Aboriginal resistance was fierce and while establishing the run, Fleming and his men had a large battle with the local Mandandanji people killing around fifty of them.

[12] In the early 1850s, their managers on these properties, James Norman, Dick Walker and D.W. Duncomb, participated in further killings of Aboriginal people including large massacres at Yamboucal and Donga Creek where troopers of the Native Police were utilised.

[24][6][25] Fleming returned to politics on 7 August 1866, when the Premier of Queensland and member for West Moreton, Robert Herbert, resigned.

He held the seat until 2 July 1867 (the 1867 election) when he was defeated by Joshua Peter Bell (sitting member), Patrick O'Sullivan and George Thorn.
