Starset is an American rock band from Columbus, Ohio, formed by Dustin Bates in 2013. They released their debut album, Transmissions, in 2014 and their second album, Vessels, on January 20, 2017. The band has found success in expanding the ideas of their concept albums through social media and YouTube, with the band generating over $230,000 in revenue from views from the latter as of November 2016. Their single "My Demons" had accumulated over 280 million YouTube views in the same time period. Their most commercially successful song, "Monster", peaked at number 2 on the US Billboard Mainstream Rock chart in May 2017. A third studio album, Divisions, was released on September 13, 2019, with their fourth studio album, Horizons, released on October 22, 2021. Their fifth album, Silos, was released September 12, 2025.

Starset was formed in 2013 by Downplay vocalist Dustin Bates, who is the band's lead singer, songwriter, and keyboardist. Bates's interest in astronomy was first fueled when acquiring his master's in electrical engineering as he studied at Ohio University. He completed research for the US Air Force and also taught at the International Space University. Bates created the fictional backstory for the band that forms the thematic basis for their music and multimedia. In the backstory, Starset was formed as part of a public outreach initiative by the Starset Society, whose aims were to alert the public about the contents of "the Message" the society obtained from a mysterious signal from space. Starset treats their backstory and the Starset Society as real in interviews, with few exceptions.

The band released their debut album, Transmissions, on July 8, 2014. The release debuted at number 49 on the US Billboard 200 charts, making it one of the highest debut albums for a rock band in 2014, and as of 2016, had sold over 79,000 copies. Three singles were released in promotion of the album: "My Demons", "Carnivore", and "Halo". They also performed well in the charts, reaching fifth, sixteenth, and sixteenth, respectively, on the Billboard US Mainstream Rock charts. The band later released an accompanying novel, The Prox Transmissions, further detailing Bates's fictional back-history of the Starset Society story.

Rob Graves, who produced Transmissions, announced on January 26, 2016, that the making of Starset's second record has "officially commenced". Along with the announcement of European tour dates supporting Breaking Benjamin, Starset announced their second album, which Bates said would be more stylistically diverse than the previous, ranging in genre from metal to pop. On October 4, 2016, Starset posted to their social media an image from a graphic novel produced by Marvel Comics as a tie-in to The Prox Transmissions. The 88-page graphic novel was co-written by Dustin Bates and Peter David, illustrated by Mirko Colak, and released in September 2017.

The album's first single, "Monster" was released on October 28, 2016. On November 4, 2016, Starset announced their upcoming album Vessels, which was released on January 20, 2017. The album debuted at number 11 on the Billboard 200 albums chart. The band spent much of 2017 touring in support of the album. The band toured with Black Satellite in the first half of 2017. In July 2017, the band performed at Seether frontman Shaun Morgan's "Rise Above Fest", alongside Shinedown and Halestorm. A second single from the album, "Satellite", was released in August 2017, peaking at number 12 on the Billboard Mainstream Rock Chart.

The band would continue touring through the first half of 2018, though Bates said he would likely take a break before pursuing a third album with the band. Instead, he was planning on releasing music under a different project name, MNQN, which would be far more electronic-based. Bates stated that he also had been working on some progressive rock–styled music that he intended to release as well, though he did not disclose when, or if, it would be released under the Starset name. In April 2018, the band announced that they had signed to Fearless Records and released a music video for the Vessels track "Ricochet". An alternate acoustic recording of the song was also released shortly after.

In August 2018, the band released a second version of the Vessels track "Bringing it Down" and announced a deluxe edition of the album, titled Vessels 2.0. Nine new tracks appeared on Vessels 2.0, consisting of "reimagined", acoustic, and remixed versions of songs from the original Vessels along with a cover of "Love You to Death" by Type O Negative. The album was released on September 28, 2018. The press release for Vessels 2.0 also stated that the band had plans to release their third studio album in 2019. MNQN's self-titled debut album released on April 4, 2019, and a live date at the Wonderbus Music and Arts Festival in Columbus, Ohio, on August 18, 2019, was announced. Much like Starset, the MNQN project features a fictional backstory, based on the titular artificial intelligence created by the Sentience Corp.

On May 13, 2019, Starset announced that the third album would be released on September 13, 2019, along with fall tour dates for the United States. Spring 2020 tour dates for Europe and the UK were announced on July 2, 2019. The album's name, Divisions, was announced in August 2019 alongside the release of its first single, "Manifest". On September 5, 2019 guitarist Brock Richards and violinist Siobhán Richards (née Cronin) were married. The album was released on September 13, 2019. By 2020, the band had received two billion streams worldwide. Due to the COVID-19 pandemic in 2020, most of Starset's tours were first postponed and later cancelled. However, Starset released the reimagined version of the single "TRIALS" and the remix version of "WAKING UP" in August 2020 and December 2020
