Tree (stylized as TREE) is the seventh Japanese studio album (fourteenth overall) by South Korean pop duo Tohoshinki, released by Avex Trax on March 5, 2014. The record was released in four physical versions, each with a seasonal theme cover – Version A (Spring/Summer), a CD+DVD version with music videos; Version B (Autumn), another CD+DVD version with off-shot movies; Version C (Winter), a CD only version with two bonus tracks; and Version D, a fan club limited edition with a CD-Extra. Musically, Tree is a varied pop music album that is influenced by a broad range of musical genres, such as electronic dance music, hip hop, R&B, swing jazz, rock music, power ballads, and reggae. Recording for the album began well before the launch of their sixth Japanese studio album Time in early 2013.

Tree was Tohoshinki's fourth consecutive album to debut at number one on the Oricon Albums Chart and the Billboard Japan Top Albums, selling 225,000 copies on its first week of release. With Tree, Tohoshinki became the first foreign group in Japan to have three consecutive studio albums with first-week sales of over 200,000 copies, breaking Bon Jovi's thirteen-year record. Less than four weeks after release, the album earned a platinum certification by the Recording Industry Association of Japan (RIAJ) for shipments of over 250,000 copies.

All four of the album's commercially successful singles – "Ocean", "Scream", "Very Merry Xmas", and "Hide & Seek / Something" – debuted at number two on the Oricon Singles Chart and achieved gold certifications by the RIAJ. To promote the album, Tohoshinki embarked on their seventh nationwide tour, Tree: Live Tour 2014 from April to June 2014.
