The couple tied the knot on a farm in Somerset, England, in front of approximately 200 guests, including family and friends, according to reports.
Sienna Miller, Jake Gyllenhaal and Colin Firth were among the guests, the Daily Mail reports.
Mulligan, 26, and Mumford, 25, were childhood pen pals in London and reconnected as adults. The couple, who have been linked since 2011, became engaged in August.
They have been rarely spotted together and have stayed mum about their relationship, but a source told the Sun in February that they decided to wed in Britain because "it's where both of their families are from."
Mulligan, who is starring alongside Leonardo DiCaprio in the upcoming Baz Luhrman version of The Great Gatsby, split from Shia LaBeouf in 2010.
Mumford & Sons roots-rock album, "Sigh No More," was the sixth best-selling album of 2011.
