When you think about the most iconic, fashion-forward, and occasionally terrifying matriarchs in soap opera history, one name usually jumps to the front of the line: Kate Roberts. If you've been tuning into the peacock-exclusive (formerly NBC) drama lately, you’ve definitely seen her rocking those signature streaks in her hair and maneuvering through Salem like a grandmaster on a chessboard. But for fans just joining the ride or those who've missed a few years, there’s always that big question: who plays Kate Roberts on Days of Our Lives?
The answer is the legendary Lauren Koslow.
Honestly, it’s hard to imagine anyone else in those high-end power suits. Koslow has been the face of Kate for so long that she basically owns the character's DNA. But the history of this role is actually a bit more layered than some people realize. It's not just about one actress; it's about a legacy that spans decades of DRAMA.
The Face of Kate Roberts: Lauren Koslow’s Reign
Lauren Koslow stepped into the heels of Kate Roberts back in 1996. Think about that for a second. That’s nearly thirty years of corporate takeovers, secret affairs, and survived "deaths." She didn't just take over a role; she transformed it.

Before Koslow arrived, Kate was played by Deborah Adair from 1993 to 1995. Adair brought a different vibe—a bit more of a polished, traditional corporate feel. When she left the show to focus on her family, the writers had a massive hole to fill. They needed someone who could play "vindictive call girl turned CEO" without breaking a sweat.
Koslow was the perfect pivot. She had already established herself as a daytime heavyweight on The Young and the Restless (as Lindsey Wells) and as a founding cast member of The Bold and the Beautiful (as Margo Lynley). She brought this edgy, sophisticated, and fiercely protective energy that made Kate Roberts a "love to hate" character.
Why Lauren Koslow Still Matters in 2026
You’d think after three decades, an actress might phone it in. Not Lauren. Even now, in 2026, her portrayal of Kate remains one of the show’s strongest pillars. She’s currently embroiled in storylines involving her marriage to Roman Brady (played by Josh Taylor) and the never-ending chaos of the DiMera and Kiriakis families.

What’s wild is how Koslow handles the "resurrection" trope. In Salem, nobody stays dead, but Kate makes it look like a minor inconvenience. Whether she’s being "killed" by a toxin or held captive in Greece, Koslow plays the aftermath with this gritty realism that keeps the stakes feeling high.
- The Look: Those blue and purple hair streaks? Pure Koslow. She actually helps style the character's iconic aesthetic.
- The Range: She can go from a heartbroken mother to a cold-blooded blackmailer in roughly 2.5 seconds.
- The Longevity: She is one of the longest-serving cast members currently on the canvas.
What Most People Get Wrong About Kate’s History
A common misconception is that Kate Roberts has always been the villain. If you look back at the early 90s, she was often the victim of the truly vile Curtis Reed. The "wickedness" people associate with her today was actually a defense mechanism. She learned that to survive Salem, you have to be the smartest person in the room.
Another weird bit of trivia? Some fans confuse this Kate Roberts with a 1970s character named Dr. Kate Winograd. While the names are similar, they are totally different people. Our Kate—the one played by Koslow—is the mother of the "next generation" heavy hitters like Lucas Horton, Philip Kiriakis, Billie Reed, and Austin Reed.

The Deborah Adair Era: Where it All Started
We can't talk about who plays Kate Roberts without giving flowers to Deborah Adair. She originated the version of Kate that first walked into Titan Industries and caught Victor Kiriakis' eye. Adair’s Kate was the one who had to deal with the initial shock of her "dead" children, Austin and Billie, showing up in town.
When Adair left in 1995, the character was actually presumed dead for a while after a plane crash (classic soap move). When the character "returned from the dead" in early 1996, it was Koslow behind the wheel. The transition was so seamless that many younger fans don't even know there was another Kate before her.
Actionable Insights for Fans
If you're trying to keep up with Kate’s current arc or just want to dive deeper into Lauren Koslow’s world, here is what you need to do:
- Watch the Peacock Archives: If you have the premium tier, go back and watch the "classic" episodes from the late 90s. Seeing Koslow’s early days as Kate gives you so much context for her current rivalry with Vivian Alamain.
- Follow the Style: Lauren is a huge fan of costume design (she actually has a degree in it!). If you love Kate’s wardrobe, check out Lauren’s social media where she often talks about the "art" of the soap opera look.
- Check the Credits: Don't just look for "Days." Koslow has done some cool voice work and guest spots on shows like Criminal Minds: Suspect Behavior and The Nanny.
Bottom line: Lauren Koslow isn't just playing a part; she’s built an institution. Whether she’s running a company or running for her life, she remains the definitive version of Kate Roberts. If you’re watching Days of Our Lives today, you’re watching a masterclass in how to keep a soap character relevant for thirty years.
