"On the Ground" is the debut solo single by New Zealand and South Korean singer Rosé from her debut single album R (2021). It was released through YG Entertainment and Interscope Records on 12 March 2021, as the lead single from the album. It was written by Rosé alongside Amy Allen, Raúl Cubina, Jon Bellion, Jorgen Odegard, Teddy, and was produced by the latter three alongside Ojivolta and 24. The song is an electropop, pop rock and pop track with synth-pop elements. Its lyrics reflect Rosé's rise to fame, from singing and playing piano in her childhood home to flying to South Korea and forming one of K-pop's biggest acts.
"On the Ground" received generally favourable reviews from music critics, who complimented its lyrics and Rosé's vocals. Commercially, it became the first song by a solo K-pop artist to reach number one on both the Billboard Global 200 and Global Excl. US charts, and earned Rosé a Guinness World Record as the first artist to top the chart as a soloist and as part of a group. The song peaked at number four on the Gaon Digital Chart and number three on the Billboard K-pop Hot 100 in South Korea, and topped the charts in Malaysia and Singapore. It also became the highest-charting song at the time by a female K-pop soloist on the US Billboard Hot 100, the Canadian Hot 100, and the UK Singles Chart.
An accompanying music video, directed by Han Sa-min, premiered the same day as the song's release. Upon release, the music video broke several YouTube records for a solo K-pop artist, including for the most-watched premiere and the most views within 24 hours for a music video, accumulating 41.6 million views in that time, for which she received another Guinness World Record. Rosé promoted "On the Ground" with performances on The Tonight Show Starring Jimmy Fallon and several South Korean music programs including M Countdown, Inkigayo, and Show! Music Core. The song received several accolades, including Best Dance Performance at the 2021 Mnet Asian Music Awards.
