The tragic news was confirmed by her daughter, Lisa Mordente, who said she passed away in New York following a brief illness.

Born Dolores Conchita Figueroa del Rivero Anderson, Chita famously forged a path for Latina artists ... becoming the first person to play Anita in "West Side Story" in 1957 and Velma Kelly in "Chicago."

She earned a staggering 10 Tony nominations during six decades on stage ... bagging the Best Actress in a Musical award for both "Kiss of the Spider Woman" and "The Rink."

Chita also starred in Broadway productions of "Threepenny Opera," "Kiss Me Kate," and "Sweet Charity," among many others.

Most recently, she was dancing onstage in the 2015 production of "The Visit" ... telling AP at the time she didn't know what she'd do if she wasn't moving, telling a story, or singing a song -- adding performance was "the spirit of my life."

Chita was also a recipient of the Presidential Medal of Freedom and became a NY Times bestseller in 2023 with the release of her book, "Chita: A Memoir."

She's survived by her daughter Lisa Mordente, siblings Julio, Armando, and Lola del Rivero, and her many nieces and nephews.

Her rep, Merle Frimark, revealed in a statement her funeral would be private and a memorial service would be announced in due course.

Chita was 91.
