SB19 is a Filipino boy band formed in 2018, consisting of Pablo, Josh, Stell, Ken, and Justin. They are noted for their contributions to the contemporary Pinoy pop scene. Now a self-managed group under 1Z Entertainment, a company they established, SB19 members are actively involved in the creative process, including songwriting, choreography, music video direction, and production.

After several years as trainees, SB19 debuted in 2018 with the single "Tilaluha". They received little attention from the public until the video of their dance rehearsal for their song "Go Up" went viral in late 2019. This led them to strategically use social media to expand their reach and recognition as well as to increase their fandom. They became the first Southeast Asian act to be nominated on the Billboard Music Awards, and the first Southeast Asian act to make an appearance in the top 10 of the Billboard Social 50. For their significant contributions in pioneering Philippine pop music to the global scene, SB19 has been dubbed the "Kings of P-pop" by the public and various media. The group promotes its music as part of Pinoy pop, a sub-genre of Original Pilipino Music.
