BBC Three is bringing the series back to its Cotswold roots on Thursday 23 January - and tickets are completely free.
Fans will get to see the first two episodes of the new series followed by a Q&A with sibling stars Daisy and Charlie Cooper, producer Simon Mayhew-Archer and director Tom George.
It will be hosted by BBC Points West Gloucestershire reporter Steve Knibbs.
Tickets to the event at Bingham Hall, Cirencester, will be allocated though a random ballot. You can apply for tickets from 10am on Friday 3 January to 10am on Friday 10 January.
To apply go to the BBC Shows and Tours website and click on the 'Shows' page.
Charlie Cooper, who plays Lee 'Kurtan' Mucklowe says: “We are so excited to have the screening of series three here in our hometown Cirencester, where the show was created. Some would call it a homecoming but the problem is we’ve never left. Big up the Cotswolds!”
This Country follows cousins Kerry and Lee 'Kurtan' Mucklowe through their quiet country lives.
At the 2018 BAFTAs This Country won the award for Best Scripted Comedy and Daisy won Best Female Comedy Performance. More than 33 million people have requested the show on iPlayer.
The new series airs in early 2020.
Stephanie Marshall, Head of the BBC in the West and South West, says: “We love bringing national series like This Country back to where they were made. It’s a way of thanking people in the area by giving them a sneak peek before the rest of the UK.
“Amazingly more than 4,000 people applied for tickets to the This Country screening last year.
“The BBC is committed to make more and more of its TV, radio and online content outside of London. In fact, more than 50% of all our shows are now made outside of the capital.”
