The drama, adapted from American author Diana Gabaldon’s best selling series, is set in Scotland and has a huge global audience which has generated millions of pounds for the country’s creative and tourism industries.
Tourism chiefs last night said the new series would continue to increase visitor numbers to Scotland.
The Sony-Starz series features Sam Heughan as 18th-century Scottish Highlander Jamie Fraser and time-travelling Second World War nurse Claire Randall Fraser, played by Caitriona Balfe, with much of the action based around the time of the Jacobite Rebellion.
The third instalment of the television show will be based on Gabaldon’s novel entitled Voyager.
A spokeswoman at Amazon Prime confirmed that, as with the first two series, the new episodes will only be available in the UK through its paid for service.
The star of the show, Scottish actor Sam Heughan, told fans on Twitter he was “excited” following the announcement.
Starz CEO Chris Albrecht said: “Outlander is like nothing seen before on television,
“We are thrilled and honoured to be able to continue the story that began with author Diana Gabaldon, and is brought to life by the incredibly talented Ronald D Moore.
“There are no better storytellers for Outlander than this team.”
