Betty McGuire, the character actress best known for playing warm-hearted grandmother Kate Malone on the sitcom Growing Pains, has died at the age of 100. Her death on October 8 at the Motion Picture & Television Fund’s Wasserman Campus in Woodland Hills closes a long career that quietly threaded through several decades of American television.
McGuire’s portrayal of the elder Malone — mother to Joanna Kerns’ Maggie Seaver and grandmother to the Seaver children — was a recurring presence on the ABC comedy, which aired from 1985 to 1992. She returned to the series across multiple seasons, appearing in a total of 12 episodes and providing a steady, familial anchor in a show defined by its domestic storylines.
According to reports, McGuire died of natural causes. The Motion Picture & Television Fund residence where she spent her final days is a longtime retirement community for performers and industry workers. No immediate survivors were listed.
Career highlights
Beyond the role that made her familiar to ’80s and ’90s viewers, McGuire built a reliable career as a guest and supporting actress. She turned up in single-episode roles on many high-profile series and took on longer arcs in other dramas, demonstrating the versatility that character actors often bring to television.
- Notable recurring roles: Hill Street Blues; Falcon Crest
- Guest appearances: 7th Heaven; ER; CSI: Miami; Murder One; Murphy Brown; Star Trek: Deep Space Nine; Charlie’s Angels; Little House on the Prairie; Hart to Hart

Character actors like McGuire rarely headline shows, but they shape the texture of television storytelling. Her steady presence across genres — from family sitcom to procedural drama and even science fiction — made her a familiar face to multiple generations of viewers.
Her death is a reminder of the many performers whose careers are measured not in marquee billing but in longevity and range. Fans of classic network television will recognize McGuire for the quiet credibility she brought to small but memorable parts.
