The 2019 FIA World Cup for Cross-Country Bajas was the first season of the reformed FIA World Cup for Cross-Country Bajas; an annual competition for baja-style rally raid events for cars, buggies, side-by-sides, and trucks held in multiple countries. The championship was last held in 2010, after which the baja events were combined with the longer cross-country rallies to form the FIA World Cup for Cross-Country Rallies.
The 2019 edition of the world cup featured eight cross-country baja events. The longer cross-country rally events remained part of the regular Cross-Country Rally World Cup. Some events on the schedule were shared with the 2019 FIM Bajas World Cup.
The FIA awarded the world cup to drivers, co-drivers, and teams competing in the T1 category; whilst drivers and teams in the T2 and T3 categories were awarded FIA cups.
In order to score points in the Cup classifications, competitors must register with the FIA before the entry closing date of the first baja entered.
