Showrunner Caroline Dries announced the cancelation on Twitter. "Just got the sad news that [Batwoman] will not be seeing an S4," she wrote. 

"I am bummed, but full of gratitude. What an honor to make 51 episodes. So many inspiring, brilliant people contributed to this series. Thank you producers, cast and crew. Thank you."

Batwoman aired its Season 3 finale, or its series finale, on March 2. News of Batwoman's cancellation comes after The CW renewed only two of its Arrowverse shows for additional seasons 

which consist of The Flash and Superman & Lois, which left the future of Batwoman up in the air. Recent reports suggested that only two of The CW's remaining DC shows  

would be renewed for additional seasons. With Batwoman off the table, that leaves Gotham Knights, Legends of Tomorrow and Naomi. 

The CW broke new ground in casting Leslie as not only the first Black, live-action Batwoman but DC's first time casting a Black woman as the lead hero in a television series.  

This is also the second time the character has been written as an out lesbian. In a January 2021 interview,  

Leslie addressed her historic role by saying, "I always just remind myself that my purpose isn’t for me. My purpose is to empower other people."
