Eric Dane, best known for his role as Dr. Mark “McSteamy” Sloan on “Grey’s Anatomy,” died Thursday at 53 after battling amyotrophic lateral sclerosis, his family announced.
Dane spent his final moments with his wife, actress Rebecca Gayheart, and their daughters, Billie, 15, and Georgia, 14, according to a statement issued by his representative.
“With heavy hearts, we share that Eric Dane passed on Thursday afternoon following a courageous battle with ALS,” the 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 native made his ALS diagnosis public in April 2025. The degenerative neurological condition affects roughly 1 in 300 Americans, and most patients survive three to five years after diagnosis.
After revealing his diagnosis, Dane became a vocal supporter of ALS research and awareness. In September 2025, he met with Rep. Eric Swalwell to discuss the disease, telling the congressman he hoped to “ring every bell” so he could watch his daughters graduate, marry, and possibly have children of their own.
The condition progressed quickly. By June 2025, Dane had lost full use of his right arm. In a conversation with ABC’s Diane Sawyer, he explained: “My left side is functioning; my right side has completely stopped working.”
Even as his physical abilities declined, Dane stayed committed to acting. During a December I Am ALS panel, he shared that he intended to keep working however he could, noting that he still had full cognition and speech and was eager to take on any role possible.
Dane’s career stretched over thirty years, beginning with a 1991 appearance on “Saved by the Bell.” Early stints on “The Wonder Years,” “Married with Children,” and “Roseanne” paved the way for roles in “Charmed,” “X-Men: The Last Stand,” “Marley & Me,” and “Burlesque.”
His breakout came in 2006 when he joined “Grey’s Anatomy” as Dr. Mark Sloan, the charismatic plastic surgeon who quickly became a fan favorite. The nickname “McSteamy” entered pop culture, and Dane remained on the show from 2006 to 2012, returning briefly in 2021. His character died in the Season 9 premiere after injuries from a plane crash.
Following “Grey’s Anatomy,” Dane starred as Captain Tom Chandler on TNT’s “The Last Ship” for five seasons from 2014 to 2018, showcasing his talents as an action lead.
In 2019, he took on a more complex role as Cal Jacobs in HBO’s acclaimed drama “Euphoria.” He filmed the upcoming third season, set for release April 12, 2026, from a wheelchair due to the progression of his illness.
Dane’s later work became deeply personal. In November 2025, he appeared in NBC’s “Brilliant Minds” as a firefighter secretly battling ALS. Showrunner Michael Grassi said the cast and crew gave him a 10-minute standing ovation after a major scene, praising the performance as “so beautiful and so honest and so real.”
ALS ultimately forced Dane to limit his public engagements. He missed the 2025 Emmy Awards after a fall at home that required stitches. And in January 2026, he canceled an appearance at an ALS Network gala where he was scheduled to receive the Dean and Kathleen Rasmussen Advocate of the Year Award.
Throughout his illness, Dane remained dedicated to advocacy, recognizing the significance of his public platform. During an I Am ALS panel, he shared that telling his story had become essential because his life no longer felt like it belonged solely to him.
ABC and 20th Television, producers of “Grey’s Anatomy,” released a joint tribute honoring Dane’s talent and strength. HBO also paid tribute, with “Euphoria” creator Sam Levinson describing him as a “dear friend” whose memory would continue to be “for a blessing.”
Dane’s personal history included profound loss. His father died from a self-inflicted gunshot wound when Dane was seven, an event that deeply shaped how he approached fatherhood with his own children.
His family asked for privacy as they grieve, noting that Dane “adored his fans and is forever grateful for the outpouring of love and support he’s received.”
Dane leaves behind an extensive body of work across film and television, from his 2024 appearance in “Bad Boys: Ride or Die” to his defining portrayal of the unforgettable “McSteamy.” More importantly, he leaves a legacy of resilience and advocacy in the face of one of medicine’s most challenging diseases.
