"The Remedy (I Won't Worry)" is the debut single of American singer-songwriter Jason Mraz from his debut album, Waiting for My Rocket to Come (2002). Written by Mraz and production team the Matrix (Lauren Christy, Scott Spock, and Graham Edwards), the song is about a good friend of Mraz's, Charlie Mingroni, being struck with cancer and how it changed Mraz's outlook on life. Occasionally, while performing this song during his shows, Mraz would include a singalong with the audience to Oasis's "Wonderwall".

Released on January 27, 2003, this song was Mraz's first top-40 hit, reaching number 15 on the US Billboard Hot 100. He would not have a second until 2008's "I'm Yours." Outside the United States, the song reached number 32 in New Zealand and became a minor hit in Australia, the Netherlands, and the United Kingdom.
