The Batangas City Tanduay Rum Masters are a professional basketball team based in Batangas City, Batangas. The team competes in the Maharlika Pilipinas Basketball League (MPBL) as a member of the league's South Division. They are one of five active teams based in the Calabarzon region and play their home games at Batangas City Sports Coliseum.
The team joined in 2018 as one of the founding teams of the MPBL, backed by Tanduay Distillers as part of the beverage company's athletics program, having previously owned a team in the Philippine Basketball Association. The team first went by the Batangas City Athletics before changing to Batangas City Embassy Chill in 2022 to promote one of Tanduay's own products. The team later changed its name to the Tanduay Rum Masters in 2024. The Batangas City franchise has also played in FilBasket.
One of the most successful teams in the MPBL, Batangas City won the inaugural championship in 2018 and has made three Division Finals appearances. They currently have the second-highest all-time regular season winning percentage among active teams at .717, only behind the San Juan Knights. To date, they are the only MPBL team to make a playoff appearance in every season of the league's existence.
Tanduay's involvement with basketball can be traced back to the Tanduay Rhum Masters that played in the Philippine Basketball Association (PBA) from 1975 to 1987 and again from 1999 to 2001.
In 2018, the Batangas City Athletics were founded as one of the league's ten charter teams. With a record of 8-1, Batangas City captured the league's best record and made it to the 2018 MPBL Rajah Cup Finals, where they beat the Muntinlupa Cagers, three games to one, to become the inaugural MPBL champions.
In the 2018–19 season, Batangas City ended the season with a record of 13-10 to claim the second seed in the Southern Division. The team failed to defend their championship, after they lost to the Davao Occidental Tigers in the Division Finals in three games.
In the 2019–20 season, Batangas City made their third straight playoff appearance with a record of 19-11, but lost to the Zamboanga Family's Brand Sardines in the First Round in three games.
The team opted out of the 2021 Invitational before returning in 2022, in which the team was renamed to Batangas City Embassy Chill. With a 17-4 record, the team made their fourth straight playoff appearance, once again making a run to the Division Finals, where they would once again fall to Zamboanga in three games.
For the 2023 Preseason Invitational, the team was temporarily renamed as the Batangas City Tanduay Rum Masters.
As the MPBL postponed its fourth season to 2022, the Tanduay-backed franchise were among the teams that took part in FilBasket. The team first took part in the 2021 Subic Championship. The Athletics finished 8th, but lost to eventual champions AICC Manila.
Right before the 2022 MPBL season, the franchise took part in the succeeding 2022 Summer Championship, marking the franchise's first professional outing. As the Tanduay Rum Masters, the team finished the elimination round 11–0, winning every game. During the playoffs, they first beat Muntinlupa in the Quarterfinals but would get swept by the fifth-seeded San Juan Knights in the Semifinals.
