The Hearts Sold Separately Tour was a concert tour by American singer Mariah the Scientist in support of her fourth studio album, Hearts Sold Separately (2025). Produced by Live Nation, the tour began on January 12, 2026, in Paris, France, and concluded on May 23 in Honolulu, Hawaii. It included performances in Europe, North America and Australia. The set list primarily featured songs from Hearts Sold Separately, alongside material from her earlier releases. 4Batz and Akia appeared as opening acts on selected North American dates, while Chxrry performed at selected European shows.
On September 15, 2025, Mariah announced the Hearts Sold Separately Tour in support of her album of the same name. Produced by Live Nation, the initial itinerary comprised 36 cities, beginning in Paris on January 12, 2026, before continuing through the United Kingdom and the Netherlands. The North American leg was scheduled to begin in Miami Beach, Florida, on February 13, with the original announcement listing an April 10 conclusion in Atlanta. Additional performances were subsequently added in several cities, including London, Utrecht, Miami Beach, Orlando, Toronto, Los Angeles and Atlanta. The Chesterfield, Missouri, concert, originally scheduled for March 15, was rescheduled for the following day. 4Batz and Akia performed as opening acts on selected North American dates. Chxrry appeared as an opening act in Manchester.
In January 2026, additional Australian performances were announced for May. The shows began at the Hordern Pavilion in Sydney on May 9, with a second performance added for May 10, before continuing to Brisbane and Melbourne. The tour subsequently included two performances at The Republik in Honolulu on May 22 and 23, with the first listed as sold out.
On March 4, 2026, Mariah reported that the tour had sold 125,000 tickets, writing, "125k tickets sold all on my own." She also described the concerts as sold out. The figure was reported during the North American leg and did not include a dollar gross.
Reviewing the Philadelphia performance at The Met, Susanna Coyle of WHIP Radio wrote that Mariah's "voice was steady and smooth throughout the entire performance" and noted that the crowd's energy remained consistent throughout the show. Kahn Santori Davison of Metro Times, reviewing the Detroit concert, described Mariah as "a singer's singer" and praised her vocal performance. He noted that the production emphasized singing rather than elaborate staging, writing that there were "no choreographed dancing or acrobatic type theatrics, just singing." Davison also observed that the audience's participation occasionally made it difficult to hear her vocals. Reviewing the Melbourne performance at Festival Hall, Walton Wong of Scenestr described Mariah's vocals as "properly arresting". The review praised the audience's enthusiasm and the balance between songs from the album and earlier material, although it noted that she appeared almost 40 minutes after the scheduled start time.
In a radio interview published in April 2026, Mariah addressed criticism of the choreography introduced during the tour. She explained, "At the beginning of my tour, I was incorporating dancing because I wanted to do something different," adding that her previous dance experience was limited.
The set list varied between performances. During the February 27 concert at Radio City Music Hall in New York City, Mariah performed "Death Do Us Part" with Fridayy and "Secrets" with A Boogie wit da Hoodie.
