"Black Heart" is a song by American hard rock band Stone Temple Pilots, released on September 18, 2013, via digital download. It is their second single to not feature their original lead vocalist Scott Weiland, and their second and final song to feature Linkin Park and Dead by Sunrise lead singer Chester Bennington. The song is also the second track that appears on their debut studio EP, High Rise, which was released on October 8, 2013 through their self-record label Play Pen, LLC. The song was also released on the same day through iHeart Radio.

In an article from Loudwire, it is described as having "a retro vibe with a main riff that's memorable and destined for a lot for radio airplay, which can follow their previous single 'Out of Time' to the top of the mainstream rock chart. The addition to the band for Bennington has been welcome for current Stone Temple Pilots' bassist Robert DeLeo, who said that 'it's been great, and a huge breath of fresh air with a lot more sanity, more reasoning, and patience.'"

Robert DeLeo states in an article from Noisecreep regarding debuting his special bass guitar on the song that "it's special for me because I just brought and found a rare bass guitar that I've been looking for in years, and I got a chance to use it for the song, so it meant a lot to me, to do that from a gear geek kind of perspective." DeLeo also stated that he has "been looking for a Rickenbacker 400 bass, and it's a very rare 1971 Rickenbacker bass. There were 20 of those made in '71, which is very rare and collectible." He also stated that "dreaming of instruments as a little kid and actually having one to use it on a song that you would put together, which means a lot."

The three remaining members (including brothers Robert and Dean DeLeo, and Eric Kretz) of the band performed the song with Bennington on The Tonight Show with Jay Leno on October 3, 2013, to promote High Rise before it was released on October 8. They also hosted a special of Rockline on October 7 that hyped their debut studio extended play that was released a day later. A video of the acoustic performance for the song by the band can be seen on the official YouTube channel, KROQ.
