The singer-songwriter is currently touring North America in support of her third album A Creature I Don't Know.
She stated that she has started recording the new album with producer Ethan Johns, and hopes to release it in early 2013.
"I finished writing a new album about a month ago," she told The Owl.
"At the moment I'm in and out of the studio working with Ethan Johns. It will probably be released in about six months."
Johns also worked with Marling on her previous album, as well as 2010's I Speak Because I Can.
Marling will play a one-off UK gig at London's Royal Albert Hall on July 7.
She will also perform at this year's Latitude Festival next month.
