Carey Mulligan received her CBE for services to drama at an investiture ceremony at Windsor Castle - with proud husband Marcus Mumford watching on.
The actress was made a Commander of the Most Excellent Order of the British Empire (CBE) in the New Year Honours list.
The 40-year-old received the honour from King Charles at a ceremony at Windsor Castle on Tuesday morning.
She later posed with the medal alongside Mumford, 39, who is lead singer of the band Mumford & Sons.
Mulligan is best known for her Oscar-nominated performances in An Education and Promising Young Woman, and for her role as Daisy Buchanan in The Great Gatsby.
Mulligan will join Daniel Craig and Meryl Streep in the cast of Greta Gerwig's upcoming Netflix adaptation of The Chronicles Of Narnia, which will be released later this year.
At Tuesday’s ceremony, the actress said working on the adaptation of CS Lewis's series of novels had been a “dream job”.
Asked who would be best to take over as 007, she added: “Oh, my gosh, that's so hard. Really hard, isn't it?
“He's got big shoes to fill. I think the thing about Daniel is that he was an extraordinary actor, I don't think he was sort of the person you would have thought of for that part.
“I think the main thing is it's just got to be someone who's an incredible actor.”
In 2010 she won the Bafta Award for best actress for her role in An Education.
She added: “I feel so unbelievably lucky to get to do a job that I really, really love.
“To have this kind of recognition on top is just sort of extraordinary to me.”
Mulligan and Mumford married in 2012 and have three children, none of whom appeared to be at the ceremony.
Also being honoured on Tuesday was Admiral Sir Tony Radakin, the former head of the military, Hilary McGrady, the director-general of the National Trust, and Valerie Lolomari, a female genital mutilation (FGM) survivor and campaigner.
Sir Tony, who served as Chief of the Defence Staff from December 2021 until September 2025, was made a Knight Grand Cross, the highest distinction in the Order of the British Empire.
Ms McGrady, who has led the conservation charity since 2018, became a CBE for services to heritage.
Lolomari has been appointed a Member of the Order of the British Empire (MBE) for services to the prevention of violence against women and girls.
She founded the charity Women of Grace and has helped more than 650 women in her work supporting FGM survivors across the country.
