Kelley Mack, the talented actress best known for her role as Addy on The Walking Dead, has died at the age of 33 following a battle with glioma, a form of cancer affecting the central nervous system.
Her family confirmed that she passed away on Saturday in her hometown of Cincinnati, Ohio. The heartbreaking announcement was made via her official Instagram page.
Mack gained recognition for her performance as Addy, a Hilltop Colony survivor in Season 9 of AMC’s hit zombie drama series, The Walking Dead, which aired between 2018 and 2019.
Beyond her work on The Walking Dead, she appeared in popular television shows including 9-1-1 (Fox, 2019) and Chicago Med (NBC, 2022). She was also a familiar face in national commercials for major brands such as Dr Pepper (notably in the fictional “Fansville” campaign), Budweiser, Dairy Queen, Chick-fil-A, Rakuten, Eli Lilly, and Ross Stores. Notably, she featured in a Rakuten advertisement alongside her real-life mother.

Described by her family as “vibrant, passionate, and full of life,” Mack was remembered for her love of storytelling and her magnetic presence on and off screen.
“Kelley’s vibrant spirit, creative passion and dedication to storytelling left an indelible mark on everyone she met and the audiences who watched her perform,” her family said in a heartfelt tribute.
Outside her acting career, Mack lived a rich and active life. She played college tennis and enjoyed hobbies such as hiking, biking, playing pickleball and piano, traveling, and participating in fantasy football leagues. She also had a deep fondness for bourbon, stuffed animals, country music, British accents, and dark chocolate. She often joked about being a “lifelong smoker,” a self-deprecating reference her loved ones say was part of her charm.
She is survived by her parents, Kristen and Lindsay; her sister Kathryn; brother and fellow actor Parker; grandparents Lois and Larry; and her beloved boyfriend, Logan.
A memorial service in her honor is scheduled to take place on August 16 at 1 p.m. at the Glendale Lyceum in Glendale, Ohio. A separate celebration of life is also being organized for her friends and colleagues in Los Angeles.
