2017–18 ABL season

The 2017–18 ABL season is the eighth season of competition of the ASEAN Basketball League. The regular season started on 17 November 2017 and ended on 28 March 2018.

Teams
Five teams from the 2016–2017 ABL season returned for this season. One team, the Kaohsiung Truth, disbanded prior to the season. One team, Mono Vampire, returned after skipping last season, having played in the 2015–16 ABL season. The team plans to concurrently play in the ABL and in the Thailand Basketball League for the upcoming season. Three teams were accepted as new members: Nanhai Long-Lions, Formosa Dreamers and CLS Knights Surabaya. The Long-Lions are the developmental team of the Guangzhou Long-Lions, the Dreamers are an expansion team from Taiwan, and the Knights left the Indonesian Basketball League to play in the ABL.

Prior their first game, the Nanhai Long-Lions renamed themselves as the Nanhai Kung Fu. After partnering with Macau's Grupo Desportivo Chong Son they changed their name once again to Chong Son Kung Fu days before the season started.

Alab Pilipinas renamed their team as the Tanduay Alab Pilipinas after securing a sponsorship deal with Asia Brewery, prior the season started.

CLS Knights Surabaya renamed their team as "CLS Knights Indonesia" prior the season started.

Tanduay Alab Pilipinas was renamed as "San Miguel Alab Pilipinas" by 1 February 2018, when the primary sponsor was changed from Tanduay to San Miguel Beer Pale Pilsen.
