South Korean boy band 2PM has released twelve studio albums, nine compilation albums, two EPs, three single albums, and twenty-eight singles (excluding twelve promotional singles and three collaboration singles). Nine of their Japanese singles and their studio album Galaxy of 2PM (2016) have been certified Gold by the Recording Industry Association of Japan (RIAJ).

2PM made their debut with "10 Out of 10" from their first single album titled Hottest Time of the Day, first released on August 29, 2008. However, it was "Again & Again" from their second single album, 2:00PM Time For Change, that propelled them to mainstream success in Korean music, solidifying their meteoric rise. Both singles were compiled for a physical release in Thailand, which topped various Thai music charts. After the controversial departure of former leader Jaebeom, the group made a comeback as a six-member group in November 2009 with the lead single "Heartbeat" from their first full-length album 01:59PM. The album ended up topping the very first issue of the Gaon Album Chart. The success of both "Again & Again" and "Heartbeat" earned them the Artist of the Year award at the 2009 Mnet Asian Music Awards.

The following year, 2PM released another single album, Don't Stop Can't Stop, and their first extended play, Still 2:00PM, both of which topped the Gaon Album Chart. On November 1, 2010, the latter debuted unexpectedly at number 13 on the Billboard World Albums Chart, though no specific promotion for the album occurred in the United States.

In 2011, 2PM debuted in Japan with the single "Take Off", which peaked at number four on the Oricon Singles Chart. Soon after, they released their second Korean album, Hands Up, which topped the Gaon Chart and spawned the hit title track of the same name. Both of the group's follow-up Japanese singles, "I'm Your Man" and "Ultra Lover", peaked at number four, while the latter became their first release to be certified Gold by the RIAJ. All three singles were included in their first Japanese album, Republic of 2PM (2011).

In 2012, 2PM rerecorded several of their old Korean-language tracks for a compilation album titled 2PM Member's Selection. That same year, they released three more singles in Japan: "Beautiful"; "One Day", a collaboration with 2AM; and "Masquerade". "Beautiful" and "Masquerade" peaked at number two and were included in the group's second Japanese album, Legend of 2PM (2013), which topped the Oricon Albums Chart.

Grown (2013), their third Korean studio album, peaked at number ten on the Oricon Albums Chart, number six on the Billboard World Albums Chart, and number one in South Korea, their third consecutive number-one Korean studio album. That same year, 2PM released two more singles in Japan: "Give Me Love" and "Winter Games". The latter was the group's first single to top the Oricon Singles Chart. Both singles were included in their third Japanese album Genesis of 2PM (2014). 2PM's fourth Korean album, Go Crazy!, was their first album not to reach the top spot in the country, peaking at number three. The Japanese version of the title track, "Midaretemina", reached number two on the Oricon Singles Chart.

2PM reached the top spot on the Oricon Singles Chart for the second time in 2015 with "Guilty Love", which along with "Midaretemina", was included in their fourth Japanese album, 2PM of 2PM. The group's fifth Korean album, No.5 (2015), topped the Gaon Album Chart and peaked at number three on the Billboard World Albums Chart—their highest rank to date. They released another Japanese single, "Higher", which was followed by their fifth Japanese album, Galaxy of 2PM (2016), their fourth consecutive number-one studio album in Japan and their first to receive Gold certification status from the RIAJ. 2PM topped the Gaon Album Chart again with their sixth Korean studio album Gentlemen's Game. The Japanese version of the title track, "Promise (I'll Be)", peaked at number two on the Oricon Singles Chart.

2PM went on hiatus from 2017 to 2021 due to mandatory military service, during which their label released three compilation albums of their songs in Japan. Furthermore, "My House", the title track of No.5, suddenly went viral in 2020. The group made their comeback in 2021 with their seventh Korean studio album, Must, which peaked at number three on the Gaon Album Chart, and their first Japanese EP, With Me Again, which peaked at number two on the Oricon Albums Chart.
