Riize (Korean: 라이즈; RR: Raijeu; stylized in all caps; pronounced as "Rise") is a South Korean boy band formed by SM Entertainment. The group consists of six members: Shotaro, Eunseok, Sungchan, Wonbin, Sohee, and Anton. Originally a seven-piece ensemble, Seunghan departed from the group in October 2024. They debuted on September 4, 2023, with the single album Get a Guitar.

The group's name, Riize, is a name created by combining "Rise", which means "growth", and "Realize", which means "a team that grows together and realizes dreams".

Members Shotaro and Sungchan previously debuted in SM's boy group, NCT, being unveiled as part of the lineup in October 2020. On July 1, 2022, SM Entertainment introduced Shohei, Eunseok, and Seunghan as part of their SM Rookies lineup. In November 2022, it was announced that they would star in the reality show Welcome to NCT Universe, hosted by Shotaro and Sungchan.

The first mentions of SM's new boy group came on February 3, 2023, when SM released a video detailing the company's future plans with SM 3.0. In the video, they explained that the group would be debuting in the fourth quarter of 2023, with the project led by SM Entertainment COO Tak Young-jun.

On May 24, 2023, SM released a video regarding their future plans for the group, announcing that Shotaro and Sungchan would leave NCT to join the lineup and that Eunseok and Seunghan would be making their debut, and that Shohei would not be debuting. On July 11, it was reported that the seven-member boy group were filming their debut music video for a projected September debut. In response to media reports about Yoon Sang's son Anton Lee joining the group, SM stated that they would begin revealing information about the group on August 1. On July 31, SM confirmed that the group would debut as "Riize" in September. On August 1, the member profiles of all seven members were revealed, alongside the group's Instagram.

On August 7, 2023, SM Entertainment announced that the group would be making their debut on September 4 with the release of their first single album, Get a Guitar. The album sold over a million copies in the first week of its release, earning the second most first-week sales of a rookie group's debut album.

On August 19, Riize released the web novel Rise & Realize ahead of the group's debut, in collaboration with Kakao Entertainment. Ahead of its release, Riize performed "Memories" and "Siren" at KCON LA on August 20. Riize released their pre-release single "Memories" on August 21. On September 4, SM Entertainment announced that Riize had signed a contract with RCA Records for their promotion and activities in the United States. At the debut showcase "Riizing Day: Riize Premiere", Riize announced their official fan club name to Sunz, which changes to Briize two days later due to potential negative interpretations of the name "Sunz." On September 7, the group made their official broadcast debut on Mnet's M Countdown where they performed "Get a Guitar", "Memories", and "Siren".

On October 22, it was announced that Riize would have their first comeback with the single "Talk Saxy" on October 27.
