Love Is a Four Letter Word is the fourth studio album by American singer-songwriter Jason Mraz, released April 13, 2012, through Atlantic Records. "I Won't Give Up" was released as the album's first single on January 3, 2012.
In November 2009 Mraz posted on his MySpace page plans for a new album to be recorded starting in December, stating "In 2 weeks time I will enter the studio and begin recording the next album. Only a handful of songs are written and slated but the momentum of love is with me. Every day new verses get added on. The songs are coming together piece by piece. The process is unlike any of the other records before this. It's like I'm being gifted the album without having to do the work. I'm creating that in 6 months the project will be complete and then we'll hit the road again with new sounds and new musicians."
In 2010 Mraz spent time in London, England, where he worked on songs for his new album with producer Martin Terefe and wrote with British singer-songwriter Dido. In August 2010 Mraz had a Q&A interview with Spin magazine. In the interview, he stated the current possible titles for his fourth album are Peace Canoe or The Love Album.
On December 8, 2011, Mraz told Jeff Benjamin of Billboard that the "album is finished" except for one track he was attempting to re-work as an acoustic version. He described the album as, "It's not a departure in the sound of the genre in any way, it's just different tones, different textures. Musically, I think people are going to like it. It's personal. It's melodic. And it's mellow. There's a couple of up-tempo tunes, but mostly the rhythm of the heartbeat kind of takes precedence on this record. Medium-tempo tunes; which I love. It feels more like the pace of life. At least, based on my life and what I've been doing."
On January 20, 2012, during a performance streamed live from the Bing Bar at the Sundance Film Festival, Mraz told the audience that the album's title is Love Is a Four Letter Word.
