Eric Dane, widely recognized for portraying Dr. Mark “McSteamy” Sloan on “Grey’s Anatomy,” passed away on Thursday at age 53 after a fight with amyotrophic lateral sclerosis, his family confirmed.
Dane spent his final hours with his wife, actress Rebecca Gayheart, and their daughters, Billie, 15, and Georgia, 14, according to a statement released by his representative.
“With heavy hearts, we share that Eric Dane passed on Thursday afternoon following a courageous battle with ALS,” his family said. “He spent his last days surrounded by close friends, his devoted wife, and his two beloved daughters, Billie and Georgia, who meant everything to him.”
The San Francisco–born actor publicly revealed his ALS diagnosis in April 2025. The progressive neurological disease affects about one in 300 Americans, with most patients living three to five years after diagnosis.
After sharing his diagnosis, Dane became a strong advocate for ALS research and public awareness. In September 2025, he met with Rep. Eric Swalwell to talk about the illness, saying he hoped to “ring every bell” so he could see his daughters graduate, marry, and possibly have children someday.
The disease advanced rapidly. By June 2025, Dane had completely lost the use of his right arm. In an interview with ABC’s Diane Sawyer, he said: “My left side is functioning; my right side has completely stopped working.”
Despite the decline in his physical strength, Dane remained dedicated to acting. Speaking at a December I Am ALS panel, he said he planned to continue working in whatever way he could, emphasizing that he still had full cognitive abilities and speech and was enthusiastic about taking on new roles.
Dane’s career spanned more than three decades, beginning with a 1991 appearance on “Saved by the Bell.” Early roles on “The Wonder Years,” “Married with Children,” and “Roseanne” eventually led to work in “Charmed,” “X-Men: The Last Stand,” “Marley & Me,” and “Burlesque.”
His career-defining moment arrived in 2006 when he joined “Grey’s Anatomy” as Dr. Mark Sloan, the magnetic plastic surgeon who quickly won over fans. The moniker “McSteamy” became a cultural touchstone. Dane remained on the series from 2006 to 2012, with a brief return in 2021. His character died in the Season 9 premiere from injuries sustained in a plane crash.
After “Grey’s Anatomy,” Dane headlined TNT’s “The Last Ship” as Captain Tom Chandler for five seasons between 2014 and 2018, showcasing his skills in an action-heavy role.
In 2019, he tackled a more nuanced character as Cal Jacobs in HBO’s acclaimed series “Euphoria.” He filmed the upcoming third season, set to premiere April 12, 2026, from a wheelchair due to the progression of his illness.
Dane’s later roles took on a deeply personal dimension. In November 2025, he appeared on NBC’s “Brilliant Minds” as a firefighter quietly struggling with ALS. Showrunner Michael Grassi said the cast and crew gave him a 10-minute standing ovation for a pivotal scene, calling his performance “so beautiful and so honest and so real.”
As ALS advanced, Dane had to reduce his public appearances. He missed the 2025 Emmy Awards after a fall at home that required stitches. And in January 2026, he withdrew from an ALS Network gala where he was set to receive the Dean and Kathleen Rasmussen Advocate of the Year Award.
Throughout his illness, Dane remained committed to advocacy, acknowledging the importance of using his public voice. At an I Am ALS panel, he said that sharing his journey had become necessary because his story no longer felt like it belonged to him alone.
ABC and 20th Television, producers of “Grey’s Anatomy,” released a joint statement celebrating Dane’s talent and perseverance. HBO offered its own tribute, with “Euphoria” creator Sam Levinson calling him a “dear friend” and saying his memory would continue to be “for a blessing.”
Dane’s personal life was shaped by early tragedy. His father died from a self-inflicted gunshot wound when Dane was seven, an event that profoundly influenced the way he raised his own children.
His family requested privacy as they mourn, noting that Dane “adored his fans and is forever grateful for the outpouring of love and support he’s received.”
Dane leaves behind a rich catalog of film and television work, including a 2024 appearance in “Bad Boys: Ride or Die,” as well as his iconic turn as the unforgettable “McSteamy.” Even more enduring is his legacy of resilience and advocacy in the face of a devastating disease.
