The Friday night drama, produced by Sean Hayes, will be back for another round.
NBC is keeping Grimm on its schedule.
The network has renewed the Friday night genre drama for a sixth season.
“We absolutely love what our producers and cast have accomplished over the past five seasons,” NBC Entertainment president Jennifer Salke said Tuesday in a statement. “They have created a whole new world of creatures and have a truly devoted fan base. We can’t wait to see what comes next.”
Produced in-house by Universal Television and Sean Hayes' studio-based Hazy Mills banner, season five of the fairy tale entry averages a 1.7 rating among the advertiser-coveted adults 18-49 demo and 6.4 million viewers when factoring in seven days of DVR. The drama is one of the most time-shifted on broadcast, improving by an average of 90 percent in the demo and adding more than 2.4 million viewers overall.
Created by David Greenwalt, Jim Kouf and Stephen Carpenter, the trio executive produce alongside Hayes, Todd Milliner and Norberto Barba. For Hayes and Milliner's Hazy Mills, Grimm is one of multiple series their company has on the air. In addition to Hollywood Game Night, they also exec produce midseason comedy Crowded, both for NBC.
For NBC's part, Grimm joins a roster of previously renewed series for the 2016-17 broadcast season that also includes dramas Law & Order: SVU, Chicago Fire, Chicago PD, Chicago Med, Blindspot, The Blacklist, Shades of Blue and comedy Superstore. With the addition of previously renewed The Voice, much of the network's real estate has already been mapped out. Still on the bubble are The Mysteries of Laura, The Night Shift, Undateable and rookies Crowded, Game of Silence, Heartbeat and Telenovela.
