A statement from her agent Simon Beresford said: "It is with tremendous sadness that we announce that Dame Diana Rigg died peacefully early this morning.
"She was at home with her family who have asked for privacy at this difficult time. Dame Diana was an icon of theatre, film, and television.
"She was the recipient of Bafta, Emmy, Tony and Evening Standard awards for her work on stage and screen.
He added: "Dame Diana was a much loved and admired member of her profession, a force of nature who loved her work and her fellow actors. She will be greatly missed."
The Doncaster-born star's career included roles as the Royal Shakespeare Company, on Broadway where she would win three Tony Awards, on the West End, and in countless television shows and films.
She became a household name as secret agent Emma Peel opposite Patrick Macnee's John Steed in the British TV series The Avengers, starring in 51 episodes from 1965-1969. She appeared as Countess Tracy di Vicenzo in George Lazenby's 1969 James Bond film On Her Majesty's Secret Service, the only woman to ever marry 007.
Her other films included Julius Caesar (1970), Theatre of Blood (1973), and The Great Muppet Caper (1981). In 1990, Rigg won the Best Television Actress Bafta for her role as Helena Vasey in the BBC's Mother Love. She also received a special Bafta award in 2000 for The Avengers, which was shared with the series' other female stars Honor Blackman, Joanna Lumley and Linda Thorson.
In more recent years she sent herself up in an episode of Ricky Gervais' Extras, starred opposite Matt Smith in an episode of Doctor Who, and received two Emmy nominations playing the scheming Lady Olenna Tyrell in HBO's Game of Thrones.
She received nine Emmy nominations in her career, winning for her role as Mrs Danvers in 1997's Rebecca.
She was made a CBE in 1988 and a Dame in 1994 for services to drama.
She recently completed filming on Edgar Wright's upcoming horror film Last Night In Soho, her last film role, and Wright called her "blazingly talent, fiery & funny".
What to say about Diana Rigg? I could talk about her incredible career, but for now I'll just say as a lifelong fan, it was beyond a thrill to work with her on her final film. She exceeded all my highest expectations, so blazingly talented, fiery & funny. Miss you already Dame D. pic.twitter.com/3crtUsJhla
She was last seen on screen in Channel 5's All Creatures Great and Small reboot.
Dame Diana's daughter, actress Rachael Stirling, said: "My Beloved Ma died peacefully in her sleep early this morning, at home, surrounded by family.
"She died of cancer diagnosed in March, and spent her last months joyfully reflecting on her extraordinary life, full of love, laughter and a deep pride in her profession. I will miss her beyond words".
Bafta also paid tribute to Dame Diana.
We're sad to hear of the passing of Dame Diana Rigg, BAFTA-winner for her performance in Mother Love in 1990 and joint recipient of the BAFTA Television Special Award in 2000 for The Avengers. pic.twitter.com/v0tzBczNKU
The British charity said on Twitter: "We're sad to hear of the passing of Dame Diana Rigg, Bafta-winner for her performance in Mother Love in 1990 and joint recipient of the Bafta Television Special Award in 2000 for The Avengers."
Playwrights Sir David Hare and Sir Tom Stoppard also paid their respects.
Sir David said: "Diana Rigg had a dazzling change of direction in middle age as a great classical actor. When Emma Peel played Euripides' Medea, Albee's Martha and Brecht's Mother Courage she swept all before her".
Sir Tom said: "For half her life Diana was the most beautiful woman in the room, but she was what used to be called a trooper. She went to work with her sleeves rolled up and a smile for everyone. Her talent was luminous".
It was my great joy and privilege to have known Diana Rigg. From three slightly hysterical months at the Old Vic in 'All About Mother' to writing The Crimson Horror for Diana and her wonderful daughter Rachael. Flinty, fearless, fabulous. There will never be another. RIP pic.twitter.com/2EGc4MVx0S
Theatre director Jonathan Kent said: "Diana Rigg's combination of force of personality, beauty, courage and sheer emotional power, made her a great classical actress – one of an astonishing generation of British stage performers.
"I was so fortunate to direct her in a series of great classical roles – Medea, Phedre – in Ted Hughes' version, specially written for her – Mother Courage and Dryden's Cleopatra. Her dazzling wit and that inimitable voice made her an unforgettable leading figure in British theatre."
She is survived by her daughter Stirling and grandson Jack.
