The crime drama starring Gillian Anderson and Jamie Dornan follows Detective Superintendent Stella Gibson (Anderson) who is brought to Belfast to help catch serial killer Paul Spector (Dornan).
3.5 million viewers have thus far been gripped by series one which began on the channel earlier this month. A further three instalments remain of the first run, which concludes on June 10.
Ben Stephenson, controller of BBC Drama, said: “The Fall has proved both a critical and ratings hit for BBC Two and is another reminder of the resurgence of drama on the channel.
“With more of Allan Cubitt’s intricate and thrilling plot revelations yet to unfold through the captivating performances of Gillian and Jamie, a second series is a must.
“Obviously we can’t give too much away as the first series builds to a gripping cliffhanger, but what we can say is it will be surprising and intense as the first.”
Writer and creator Allan Cubitt added: “The BBC has been an incredibly supportive partner in this project, and working with BBC NI and the Artists Studio has been the best experience of my career to date.
“I always envisioned The Fall as a returning series and wish to congratulate both Gillian Anderson and Jamie Dornan who have played their parts to perfection.”
Series two will commence production in “due course”, while series one continues tonight at 9pm on BBC Two.
