Alianza Petrolera Fútbol Club was a Colombian professional football team based in Barrancabermeja, Santander, that last played in the Categoría Primera A.

In early 2011, Alianza Petrolera signed a partnership deal with Atlético Nacional that would net them players and coaching staff on loan, with much of the wages covered by the latter team.

The series went to penalty kicks, where Alianza Petrolera prevailed and earned promotion to the top flight for the very first time.

After finishing in eighth place in the aggregate table of the 2023 Categoría Primera A season, Alianza Petrolera qualified for their first international competition, the 2024 Copa Sudamericana.

However, on 16 January 2024 the club announced their departure from Barrancabermeja due to the lack of financial support from local authorities, accepting a proposal from the city of Valledupar to move there.
