Martin Short is facing devastating heartbreak. His daughter, Katherine Hartley Short, died on Monday, February 23, 2026. She was 42 years old.
A family representative confirmed the news, saying: “It is with profound grief that we confirm the passing of Katherine Hartley Short. The Short family is devastated by this loss, and asks for privacy at this time. Katherine was beloved by all and will be remembered for the light and joy she brought into the world.” TMZ
This is a loss that cuts deeply. Martin Short has carried so much grief in his life already. To lose a child is something no parent should ever face.
What Happened to Katherine Short

Martin Short also posted a personal tribute on Facebook. He wrote: “Katherine was the light of our lives full of warmth, kindness, and a joy that touched everyone she met.” CBC News
Those words say everything. A father talking about his daughter that way tells you what kind of person she was.
Who Was Katherine Short
Katherine mostly stayed out of the spotlight despite her famous father. She carved her own path in a completely different world from Hollywood.
Katherine Short earned a bachelor’s degree in psychology and gender sexuality studies from New York University in 2006. ABC7 She later received her master’s in social work from USC. After her master’s program, Katherine worked at UCLA’s Resnick Neuropsychiatric Hospital for four years, becoming an expert in crisis management, advocacy, connecting clients to resources, individual therapy, group psychotherapy, and supporting family members of persons with severe mental illness or substance abuse.

She then moved to the Camden Center, a mental health clinic in West Los Angeles, before starting her own private practice. This was a woman who dedicated her life to helping others through their darkest moments.
Katherine was also a mental health advocate and was involved with the charity Bring Change 2 Mind. ABC7 That organization works to break down the stigma around mental health. The fact that she gave so much to that cause makes this loss even harder to process.
I find it both heartbreaking and meaningful that Katherine spent her career helping people in crisis. She understood pain. She worked every day to ease it for others.
A Family That Knows Grief
Katherine was the oldest of Martin and Nancy’s three children. She is survived by her brothers Oliver Short, 39, and Henry Short, 36. E! News
Katherine’s mother, actress Nancy Dolman, died of ovarian cancer in 2010. Variety Martin Short and Nancy were married for 30 years. Her death hit the family hard.
Martin spoke about that loss to The Guardian in 2012. He said: “It’s been a tough two years for my children. This is the thing of life that we live in denial about, that it will ever happen to us or our loved ones, and when it does you gain a little and you suffer a little.” TODAY.com
Now that grief has doubled for this family. There are no words adequate enough for what Martin Short and his sons are going through right now.
Martin had also spoken over the years about keeping his family tight. He told CNN in 2013 that he was inspired by his own childhood to make sure his children were always close. “When you have kids you have to just set down this bottom line of what can’t happen,” Short said. “Everyone has to like each other and get along. And if you don’t, you’ll get the wrath of the parents.” ABC7
That closeness makes this loss even more devastating for the family left behind.
Martin Short’s Upcoming Shows Postponed

That’s the right call. No one should be expected to perform comedy while grieving their child. Steve Martin and Martin Short have been close friends for decades. I imagine Steve is also heartbroken right now.
A Life Devoted to Others
Katherine Short was not a celebrity. She was a social worker. She was a mental health advocate. She was a daughter, a sister, and a friend to many.
She spent years working with people who were struggling. She showed up for strangers in their worst moments. That kind of quiet dedication is its own form of greatness.
Martin Short has faced unimaginable loss. He lost his wife. He lost his close friend Catherine O’Hara last month. And now he has lost his daughter.
The Short family has asked for privacy. That request deserves to be honored fully and completely. This is a time for grief, not public consumption.
Katherine Hartley Short was 42 years old. She will be remembered for the light she brought into the world and the lives she touched through her work.
