Simon Fraser (20 May 1776-18 August 1862) was a fur trader and an explorer who charted much of what is now the Canadian province of British Columbia. Fraser was employed by the Montreal-based North West Company. By 1805, he had been put in charge of all the company's operations west of the Rocky Mountains. He was responsible for building that area's first trading posts, and in 1808 he explored what is now known as the Fraser River, which bears his name. Simon Fraser's exploratory efforts were partly responsible for Canada's boundary later being established at the 49th parallel (after the War of 1812), since he as a British subject was the first European to establish permanent settlements in the area.

Simon Fraser is a British comics artist best known for his work on Nikolai Dante, a series he created with writer Robbie Morrison in 2000 AD.

Sir Simon Fraser (21 August 1832 - 30 July 1919), Australian politician, was a member of the Australian Senate and the grandfather of Malcolm Fraser, Prime Minister of Australia from 1975 to 1983.

Fraser was born in Pictou in Nova Scotia, Canada, the son of a Scottish timber miller and farmer. When he was 21 he emigrated to the goldfields of Victoria in search of his fortune. After a time prospecting in Bendigo he became a contractor, soon moving into railways and becoming by the 1870s a wealthy man. He bought extensive estates in the Western District of Victoria and became a leader of the wealthy wool-growing class known as the squatters.

Fraser was elected to the Victorian Legislative Assembly for the seat of Rodney in 1876 where he served until 1883. He was elected to the Victorian Legislative Council, the traditional preserve of the squatters, for South Yarra Province in 1886, and remained a member until 1901. He was a Minister without Portfolio from 1890 to 1892. He was a Victorian delegate to the Imperial Conference in Ottawa in 1894, and a member of the Constitutional Convention which drafted the Australian Constitution.

In 1901, following the federation of the Australian colonies, Fraser was elected as one of the first six members from Victoria of the Australian Senate, where he sat until his retirement in 1913. He was elected as a supporter of Edmund Barton's Protectionist Party, but he was not a supporter of Barton's more liberal successor, Alfred Deakin, and sat as an independent conservative until 1909, when he became a member of Deakin's Commonwealth Liberal Party, although still belonging to its conservative wing. He was given a knighthood, becoming Sir Simon Fraser, in 1918.

Fraser married Margaret Bolger in 1862 and had two daughters. Following her death he married Anne Collins in 1885 and had three sons with her. One of these, Neville Fraser, inherited Simon Fraser's property at Balpool in the Riverina district of New South Wales, where his son Malcolm Fraser grew up.

Sir Simon Fraser of Oliver and Neidpath, Knight Banneret fought in the Wars of Scottish Independence.
