In early 2015, Grande embarked on The Honeymoon Tour, with shows in North America, Europe, Asia and South America. Following the tour's early success, more dates were added, and the tour concluded in October 2015 after a total of nearly 90 dates. It earned approximately $40 million and sold over 800,000 tickets. Reviews of the tour performances generally praised Grande's vocals and ability to convey emotion in the songs but found the concerts to be over-produced: "[S]ome judicious editing would've elevated the evening from surprising to satisfying and possibly even shockingly good. As it is, Grande is so busy piling on the spectacle she neglects to highlight the one thing – those deceptively powerful pipes – setting her apart from her contemporaries."

Grande was featured on Cashmere Cat's song "Adore", which was released in March during her Honeymoon Tour; a review in USA Today said: "Grande's towering vocals have never sounded better than on this offbeat R&B track."[115] Also in 2015, Grande guest-starred on several episodes of the Fox comedy-horror TV series Scream Queens as Chanel#2.[116][117] Grande filmed an episode for the Fox TV reality series Knock Knock Live, but the show was canceled before her episode aired.[118][119]

At the Summertime Ball at London's Wembley Stadium in June, Grande performed three songs from the album as part of her set.

She also participated in the Jingle Ball Tour 2016.

Grande began her Dangerous Woman Tour in February 2017 in North America and then Europe. Reviewing the concert for Las Vegas Weekly, Ian Caramanzana wrote: "Grande's burly, soulful vibrato and wide range remain the star of her show, and she's at her best when it's just her, a microphone and her band – especially when she performs ... ballads." Jon Pareles of The New York Times called the concert "a show of confidence, prowess and aplomb. ... Her agile soprano was strong and unconcealed in every song."  After Grande's concert at the Manchester Arena in Manchester, England, on May 22, a suicide bomber detonated an explosive in the foyer of the arena, causing 23 fatalities and more than 500 injuries. Grande suspended the tour until June 7 and held a televised benefit concert, One Love Manchester, on June 4 at the Old Trafford Cricket Ground in Manchester, helping to raise $23 million to aid the bombing victims and affected families.  Grande, Justin Bieber, Katy Perry and other artists performed.  To recognize her efforts, the City Council named Grande the first honorary citizen of Manchester.
