This final series was written by the original creator Sally Wainwright.
Speaking about the show, Wainwright said: "I'm delighted to find myself back in the world of Catherine Cawood and her family and colleagues for the final instalment of the Happy Valley trilogy. It's been wonderful to see the lasting impact this series has had on audiences all over the world.
"I'm thrilled that Sarah, James and Siobhan are back on board for what I hope will be the best season yet, and thrilled once again to be working with the wonderful team at Lookout Point, the BBC and our new colleagues at AMC."
Lancashire said it was "time to let the dog see the rabbit", while Norton admitted it was a "wonderful and daunting privilege" to return to his role.
This series starts with Catherine discovering the remains of a gangland murder victim in a drained reservoir. This sparks a chain of events that unwittingly leads her straight back to Tommy Lee Royce.
As well as trying to stop a serial killer, Catherine is juggling the demands of her 16-year-old grandson Ryan, and facing the never-ending problem of drugs in the valley as she gets closer to retirement.
When will the third series of Happy Valley series be available to watch?
The release date hasn't been confirmed but since the BBC has announced that filming for this series will begin in 2022, it will be a while before it hits our screens.
