The “vocal queens” of K-pop are officially coming back together. On December 31, 2025, RBW Entertainment sent waves of excitement through the global music community by announcing a massive commemorative project for MAMAMOO’s 12th debut anniversary.
The group, consisting of Solar, Moonbyul, Wheein, and Hwasa, is set to release a full-group album in June 2026, followed by an extensive large-scale world tour.
This announcement marks a pivotal moment for the quartet, as it will be their first group release in nearly four years since their 12th mini-album, MIC ON, which dropped in October 2022.
The 12th Anniversary Project: June 2026
MAMAMOO officially debuted on June 19, 2014, and June 2026 will mark exactly twelve years of their influential career.
To honor this milestone, the members are reuniting for a project that the agency describes as a “response to the unwavering love and support” of their dedicated fandom, MooMoo.

The timing of the June release is particularly special, as MAMAMOO has a long-standing tradition of delivering high-energy, successful summer tracks like “Um Oh Ah Yeh,” “Yes I Am,” and “Egotistic.”
This upcoming album is expected to showcase the artistic evolution each member has undergone during their period of solo focus, blending their individual strengths back into the cohesive, powerful harmony that defined the group’s rise to stardom.
A Massive 26-City World Tour
Accompanying the new album is a large-scale world tour that aims to connect with fans on a global level. The tour is confirmed to span 26 cities across several major regions:
- South Korea: Launching with domestic concerts to celebrate with home fans.
- Asia: Returning to key markets where their popularity remains sky-high.
- North and South America: Reaching out to the Western fanbase that has long awaited a full-group return.
- Europe: A highly anticipated inclusion that has already sparked massive discussion among European MooMoos.
The agency stated that the tour will not only feature live stages for their new songs but will also serve as a “musical journey” through their entire discography.
Fans can expect powerful vocal performances and storytelling that encapsulate the group’s narrative since 2014.
The Power of “Trust-and-Listen MAMAMOO”
The term “믿듣맘무” (Mid-Deut-Mam-Mu), meaning “MAMAMOO you can trust and listen to,” has become a hallmark of their reputation.
This project is a reaffirmation of that title. Despite the members being signed to different agencies for their solo activities, their commitment to the group remains unshaken.

RBW will take the lead in producing the album and organizing the tour, ensuring that the signature “MAMAMOO flavor”—vocal excellence, stage confidence, and genre-bending experimentation—is preserved.
Why This Matters Now
Since their last group release, Solar and Wheein have wrapped up successful Asia tours, Moonbyul is currently on her own solo tour, and Hwasa has dominated domestic charts with hits like “Good Goodbye.”
This period of individual growth is what makes the 2026 reunion so compelling; it’s an opportunity to see how four established soloists can reinvent their group dynamics for a new era of K-pop.
For MooMoos who have navigated the “MAMAMOO drought” by supporting four separate solo careers, the announcement of an OT4 comeback is the ultimate year-end gift.
As the group prepares to hit the stage in 26 cities, the anticipation is already at a fever pitch.
2026 is shaping up to be a legendary year for the vocal powerhouse, proving that no matter how far their solo journeys take them, MAMAMOO is a force that is simply better together. Get your lightsticks ready—the queens are coming home.
