It will surpass the 20-season milestone it previously shared with "Law & Order" (1990-2010) and "Gunsmoke" (1955-75).
"As 'SVU' moves into its third decade, Mariska has become an iconic figure as a star, advocate and crusader for women," series creator/executive producer Dick Wolf said in a statement.
"She is an enduring champion of the movement to end sexual violence, and dozens of episodes have dealt with the very same issues that have shifted into the spotlight in this country in the past two years. Mariska is a delight as #1 on the call sheet and, to me, a true friend."
"I'm deeply proud to be a part of this groundbreaking show, and humbled to make television history today," added Hargitay.
"The longevity and continued success of 'SVU' is a testament not only to the show's powerful storytelling and ability to connect with viewers, but to its necessity. We have told important stories for 20 years, and we will continue to tell them."
