The announcement, made at the Netflix global fan event Tudum, comes only a week after the launch of season 3.
Post the announcement, actor Gillian Anderson, who plays the role of sex therapist Dr Jean Milburn, took to her Instagram handle and posted a BTS picture from the sets of the show.
In the group selfie, Anderson can be seen along with Asa Butterfield (Otis Milburn), Patricia Allison (Ola Nyman), Mikael Persbrandt (Jakob Nyman) and Alistair Petrie (Mr Groff), all dressed as their characters.
Anderson added the caption, "I guess we’ll be seeing you for S4!!"
