Olivia Trinidad Harrison (née Arias; born May 18, 1948) is an American author and film producer, and the widow of musician George Harrison of the Beatles.
She first worked in the music industry in Los Angeles, for A&M Records, where she met George and then helped run his Dark Horse record label.
In 1990, she launched the Romanian Angel Appeal to raise funds for the thousands of orphans left abandoned in Romania after the fall of Communism there.
Following her husband's death in 2001, Harrison has continued his international aid efforts through projects in partnership with UNICEF, and is the curator of film, book and music releases related to his legacy.
She represents his voice on the Beatles' Apple Corps board and is similarly a director of his charity organisation, the Material World Foundation (MWF).
Under the auspices of MWF, she has sponsored the preservation of film history in collaboration with American director Martin Scorsese.
These restoration projects include short films by Charlie Chaplin and works from 1940s Mexican cinema.
Harrison shared George's spiritual inclinations, and from the mid-1970s her influence was reflected in a renewed optimism in his music.
At their Friar Park home in December 1999, when she overpowered a knife-wielding intruder who had repeatedly stabbed George, her actions were recognized as having saved her husband's life.
Among Harrison's film projects, her production of Concert for George won the Grammy Award for Best Long Form Music Video in 2005, and her co-production of Scorsese's 2011 documentary George Harrison: Living in the Material World won an Emmy Award in the category "Outstanding Documentary or Nonfiction Special".
She authored books to accompany both these films, and in 2017 compiled a revised edition of George's 1980 autobiography, I, Me, Mine.
She is the mother of Dhani Harrison, also a musician.
