Sir Roderick William Cameron (July 25, 1825 – October 19, 1900) was a Canadian and American businessman noted for co-founding the R. W. Cameron and Company shipping line in New York City, as well as for his role as an official representative of Canada and Australia at several international exhibitions during the 1870s and 1880s.^[1]

Cameron was born in Glengarry County, Upper Canada on July 25, 1825 to Duncan Cameron (c. 1764–1848), a prominent fur trader with the North West Company who represented Glengarry in the Upper Canadian House of Assembly during the 9th Parliament, and Margaret MacLeod.^[2]

His paternal grandparents were Alexander Cameron and Margaret (née McDonell) Cameron.^[2] His father, along with his grandparents, immigrated to Tryon County, New York in 1773. In 1785, following the Revolutionary War, the Loyalist Camerons moved to Williamstown, Ontario in Canada.

He was tutored in Williamstown by Dr. John Rae and later at the district school at Kingston.^[3]

From 1839 to 1847, he was in business in Hamilton, Ontario, working as a clerk in a dry-goods business.^[1]

In 1852, during the Australian gold rushes, Cameron chartered a ship to take supplies and passengers from New York to Australia. Shortly thereafter, he added more ships and consolidated his business into a shipping company known as the Australian Pioneer Line. In 1870, he took on William Augustus Street as his partner, and the firm became known as R. W. Cameron and Company.^[1] The company maintained success during the Panic of 1857, the American Civil War, and the boom of the Clipper. Cameron generally focused on trade routes between New York and Australia, linking with New Zealand, England, and certain areas in Asia, transporting kerosene and farm machinery as well as Australian wool. By the end of the 1800s, the company no longer owned ships, instead they chartered them, leaving risk elsewhere.^[1]

On August 6, 1845, he married Mary Ann Cumming, the daughter of George Cumming of Quebec. She died in 1858; they had no children together.^[1]

Gen. Frederick William Cavendish, Marmaduke Furness, 1st Viscount Furness, and Valentine Browne, 6th Earl of Kenmare.^[20]
