"Left and Right" is a song by American singer-songwriter and producer Charlie Puth featuring South Korean singer Jungkook of BTS, released through Atlantic Records on June 24, 2022, as the third single from Puth's third studio album Charlie. It was co-written by Puth and Jacob Kasher Hindlin with the former also serving as producer. Available digitally and as a limited edition CD and cassette, the duet marks the second time Puth and Jungkook have collaborated, the first being their performance of "We Don't Talk Anymore" at the Genie Music Awards in 2018.

A catchy, upbeat pop song, the lyrics of "Left and Right" focus on memories of a past love and how consumed by thoughts of that former relationship one can become. An accompanying music video was released the same day as the song and shows Puth and Jungkook visiting a therapist's office for help with their lovesickness.

The single debuted at number one in India, the Philippines, and Vietnam; number two in Malaysia and Singapore; and number three in Hungary, Indonesia, and Taiwan. It peaked at number 22 on the Billboard Hot 100 in the United States and debuted at number five on the Billboard Global 200, earning Puth and Jungkook their first top-10 entries on the latter. The single also spent three consecutive weeks at number one on the Billboard Japan Hot Overseas chart. It has been certified Platinum in Canada and Gold in the US.
