"Jar of Hearts" is the debut single by American singer-songwriter Christina Perri. The song was released onto iTunes July 27, 2010, a week after its debut on So You Think You Can Dance. The song was included on Perri's debut EP The Ocean Way Sessions and is expected to appear on Perri's upcoming debut album, Lovestrong.

The song was written by the songs performer, Christina Perri, with additional writing by Drew Lawrence and Barrett Yeretsian. The songs producers also included Perri and Yeretsian. Perri drew inspiration for the song from a real-life experience with a love interest who wanted to rekindle a broken relationship. Perri's friend Keltie Colleen introduced the song to a choreographer on So You Think You Can Dance where it premiered. After its debut, the song was released onto iTunes where it later rose to the Top 20 spot in one week.

Perri was unsigned at the time of the song release, which created a lot of discussion between critics who favored the song. The song charted on multiple charts in both the United States and Canada at numbers 17 and 36 respectively. The song sold an overall of 47,500 downloads in its opening week. It was later registered for a Gold-certification by the RIAA
