Fans of the show did their part to ensure that Killjoys Season 4 will happen. “Bless the fans for everything they’re doing,” praises Michelle Lovretta. “Our numbers are going up every week, which is really, really hard in a season 3, so thank you. Keep that up!”[1]

Renewal of Killjoys for Season 4 and Season 5 was announced September 1, 2017. Like the previous seasons, they will each have ten episodes.[2]


Syfy announced that Killjoys season 4 will premiere on July 20, 2018 in the U.S. and Canada.[3]

The fourth season of Killjoys will receive its UK premiere on SYFY UK on Tuesday, August 21, 2018.[4]


Production on Season 4 began on February 2, 2018. Adam Barken, who has been a writer and producer on the series since season one, is promoted to executive producer and showrunner for Killjoys.

“We are thrilled to have 20 episodes to complete the epic story of Killjoys,” said David Fortier and Ivan Schneeberg, executive producers of Killjoys and co-presidents of Boat Rocker Studios. “Michelle created a unique show that set a new standard for being both fun and empowering, and we are excited to see Adam taking the reins."[5][6]


The Killjoys scattered to the far corners of The J Star Cluster and beyond. Dutch is on a journey to face her biggest foe yet, while D’av and John are trapped in an elevator in deep space with a pregnant Delle Seyah Kendry.[7] They are united by the knowledge of the name of their true enemy: The Lady, an immeasurable manifestation of evil without beginning or end. The Lady is making her play, and our trio has something she wants.
