The TV series sees the comic actors playing semi-fictionalised versions of themselves, travelling by car to conduct a series of luxurious restaurant reviews for a national newspaper.
As first reported by website Chortle, Steve Coogan revealed the news on the latest episode of the Off Camera With Sam Jones podcast. He confirmed to the host: "We're doing another trip next year, which is The Trip To Greece."
The series will again be directed by Michael Winterbottom, with Chortle reporting that Sky have commissioned the series.
Series 3 ended with Coogan venturing into North Africa, running out of petrol and being approached by what appeared to be a group of ISIS militants.
Coogan, who stars in Laurel & Hardy film Stan & Ollie, out in January, is currently filming Greed with Winterbottom - a comedy film about a retail billionaire. He is also due to return to the BBC early in 2019 with a new Alan Partridge sitcom. This Time With Alan Partridge was filmed earlier this year.
Further details about The Trip To Greece are expected to be revealed in due course.
