"1000hp" ("1000 Horse Power") is the lead single and title track from Godsmack's sixth studio album of the same name. 1000hp was released on June 9, 2014, and was made available for digital download on Amazon and iTunes on June 10. The single reached number one on the Billboard Hot Mainstream Rock Tracks, making it the band's seventh number one single on the chart.

In an interview with the Pulse of Radio, and regarding how the single came together, Sully Erna revealed that it was written in about an hour, stating, "It's one of those songs that surprisingly came out and was written from back to front in, like, an hour. I started putting one thing together with the next, and then Shannon Larkin started jumping in and then we arranged the whole song, and literally within an hour, maybe 90 minutes, this whole song was written and it was one of the last songs that we wrote, and it ended up becoming the first single."

When interviewed by Full Metal Jackie, Erna offered additional details as how the single came to be, stating, "We had been working on stuff that we had on our own and brought in. I go, 'You know what? We haven’t wrote anything yet, I'm just going to write a song real quick before TC gets back from dinner.' Tony, kidding around, said, 'You should make it a real fast riff because he'll be right back.' So I started playing really fast and then all of a sudden, I was like, 'Hold on. I have something going here.' I started hearing the different movements in the chords and it just started to feel like it was coming together. Then all of a sudden, within 90 minutes the whole song kind of wrote itself."

In the same interview with the Pulse of Radio, Erna revealed that the working title for the single was "100,000 Horsepower", but he felt he needed to change it, explaining, "Actually, the original title I wanted to put on the song was '100,000 Horsepower'. But unfortunately, rhythmically, it was too many syllables and I couldn't make it fit the way I wanted to creatively, so I trimmed it back to '1000 Horsepower', which is still pretty fuckin' powerful, by the way."

On August 12, the music video for 1000hp premiered on Shazam, a commercial smartphone-based music identification service. One day later, it premiered on Godsmack's official Vevo channel.
