Ourbirthday (stylized OURBIRTHDAY, abbreviated OBD) is a seven-member girl group formed by Innit Entertainment, the JYP Entertainment subsidiary that JYP launched in 2024. The line-up was revealed in two stages: Cho Hyejin, Baby and Achiraya were introduced first and released the pre-debut digital single "Hungry (Side A)" on July 22, 2026, before Kuk Chorok, Shin Hyewon, U and Kilala completed the seven-member group with the same song's "Side B" version a week later. The full line-up made its official debut on August 19, 2026 with the single album Our Birthday, led by the single "Squeezy" — JYP's first new girl group since Nmixx in 2022.

The group built its early identity around a genre its label calls "whip-hop," described as a blend of light, freewheeling energy — likened to whipped cream — and hip hop performance, tied to a set of "WHIP!" cartoon-character mascots representing each member. The debut single album carries four tracks: the title song "Our Birthday," the lead single "Squeezy," and the two pre-debut "Hungry" recordings. It opened at No. 6 on the Circle Album Chart and had sold more than 119,000 copies in Korea by late August 2026, while both "Squeezy" and "Hungry (Side A)" charted individually on the Circle Download Chart.
Having debuted only weeks before this was written, Ourbirthday has not yet released further music beyond its debut package. The seven members — three Korean, two Japanese, one Taiwanese and one Thai — held a global debut showcase, OURBIRTHDAY PARTY, on August 19, 2026, at which fellow JYP-family act Nmixx made a surprise appearance.
