Joseph Gibb Robertson (1 January 1820 – 13 March 1899) was a Scottish-born merchant, farmer and political figure in Quebec.

He represented Sherbrooke in the Legislative Assembly of Quebec from 1867 to 1892 as a Conservative.

He was born in Stuartfield, Aberdeenshire, the son of the Reverend James Robertson and Elizabeth Murray, and came to Sherbrooke, Lower Canada with his family in 1836.

Robertson established a store in Sherbrooke and speculated in land.

He resigned his seat in the cabinet in 1874 during the Tanneries scandal and again later that year because of his opposition to government ownership of the North Shore Railway.
