Frederick Thomas (Fred) Green (April 4, 1829 – May 5, 1876) was an explorer, hunter and trader in what is now Namibia and Botswana.
By early March 1852, Fred Green was back in the Orange River Sovereignty, which seems to have become the base for him and his brother Charles on their annual expeditions.
On their 1852 trip to Lake Ngami, Charles and Fred Green visited the Bakwena chief Setshele I at Kolobeng and left 50 cattle with him for their return journey.
Charles and Fred Green returned to Bloemfontein in January 1853 accompanied by Edwards, who acted as Setchele's interpreter, to lay a complaint with the British authorities in the person of their brother Henry Green, the British Resident.
Henry Green was warned in a letter by Sir George Cathcart, governor of the Cape Colony, not to listen to his brothers and espouse Setshele's cause.
Fred Green, then 23, remained in Bloemfontein, staying at Tempe with Andrew Hudson Bain, a Scots farmer who had hunted in the interior in his youth.
In the winter of 1853 Fred Green returned to the Lake Ngami area, travelling far to the east.
In March, the British garrison and civil establishment left and the Orange Free State republic came into being.
It seems likely that Fred Green thought that, in view of the changed political situation, the prospects for trade in the east were poor and so turned his face westwards.
In Cape Town Fred Green met Charles John Andersson, the Swede and entered into partnership with him.
