Her family have announced the news in a statement.
Actress Maggie Smith, known for her roles in the Harry Potter films and Downton Abbey, has died at the age of 89.
Announcing her death, her children Chris Larkin and Toby Stephens said in a statement:
“It is with great sadness we have to announce the death of Dame Maggie Smith. She passed away peacefully in hospital early this morning, Friday 27th September.
“An intensely private person, she was with friends and family at the end. She leaves two sons and five loving grandchildren who are devastated by the loss of their extraordinary mother and grandmother.
“We would like to take this opportunity to thank the wonderful staff at the Chelsea and Westminster Hospital for their care and unstinting kindness during her final days.”
Over a career spanning seven decades, Smith was one of the most esteemed names in British acting thanks to her roles in film and television.
Born in 1934, in Ilford, England, she trained at the Oxford Playhouse before making her mark in theatre and cinema, earning acclaim with both comedic and dramatic performances.
She won two Academy Awards, for The Prime of Miss Jean Brodie (1969) and California Suite (1978), along with numerous other accolades including seven BAFTAs and four Emmy Awards.
But it was for her portrayal of Professor McGonagall in the Harry Potter films that many came to know and love the actress. Smith endeared herself to a new generation with her role as the harsh but fair witch in the legendary franchise, and was one of the most popular characters in the films.
She was one of the few actors to appear in every film in the series, from 2001 to 2011.
After the Harry Potter films, Smith’s next major role came in the television, where she starred as the indomitable Dowager Countess in Downton Abbey.
She went on to reprise her role in two spin-off films, released in 2019 and 2022, cementing her place as a cultural icon.
Smith also received acclaim later in her career for her role in 2015 film The Lady in the Van, for which she received a BAFTA nomination for best actress in a leading role.
She is survived by her two sons, actors Toby Stephens and Chris Larkin.
