George Albertus Cox (May 7, 1840 – January 16, 1914) was a very prominent Canadian businessman and a member of the Senate of Canada.

He served seven years as mayor of Peterborough and accumulated real estate in that area.

In 1884, he founded the Central Canada Loan and Savings Company, moving to Toronto in 1888 and becoming president of the Canadian Bank of Commerce in 1890.

In 1901, Cox and Edward R. Wood established investment dealer Dominion Securities Corporation Limited, today a part of the Royal Bank of Canada.

A number of notable Canadians got their start in Cox companies: William Thomas White, James Henry Gundy, Edward Robert Peacock, and Frank Porter Wood, the younger brother of Edward Rogers Wood.
