"The Only High" is a song recorded by Australia pop duo The Veronicas for their fourth studio album, Godzilla (2021). The song debuted at number 79 on the Australian Singles Chart, later peaking at 41. A music video for the song was shot in London, but for unknown reasons was never released.

"The Only High" was co-written by The Veronicas' twins Jessica Origliasso and Lisa Origliasso, along with Seann Bowe and Shelly Peiken, the latter of whom collaborated with the duo on their first Australian number-one single, "Hook Me Up" ten years previously.^[1][2] On working with Peiken, Jessica said: “We just have some kind of chemistry with [Peiken] that you can’t explain. She really gets to the heart of us.”^[1]

Speaking to The Daily Telegraph about the inspiration behind "The Only High", Lisa described it as: “When you are in love, you want to shout it from the rooftop.” Regarding hers and Jessica's current love lives, Lisa added: “Jess and I are pretty open with our lives in that regard and we are very proud of our partners. We are both in very happy, committed places in our lives.”^[3]

On 31 May, a trailer was uploaded on The Veronicas official Instagram account announcing the release of "The Only High" on 2 June. In the trailer, a synth-pop "Trailer remix" of the track, remixed by Brisbane producer JOY, played in the background and featured visuals of Jessica and Lisa in a photoshoot on top of a building, next to burnt cars and surrounded by flowers.
