Lower Aragon (Spanish: Bajo Aragón, Aragonese: Baixo Aragón, Catalan: Baix Aragó), also known as Tierra Baja, is a natural and historical region in Aragon, Spain. The name "Lower Aragon" refers to the areas of the lowest altitude within the Ebro river basin, but the historical region encompasses only the river basins of several right tributaries of the Ebro River, namely the Matarranya, Guadalope, Regallo, Martín and Aguas, located between the Ebro and the Iberian mountain range.

The demonym for Lower Aragonese people is bajoaragonés or tierrabajino. The eastern fringes of the Lower Aragon natural region include some areas belonging as well to the Catalan-speaking strip in eastern Aragon known as La Franja and overlapping the historical Ilercavonia comarca.

All the villages traditionally taking part in the characteristic and loud Drum and Bass drum Route during Holy Week processions are included in Lower Aragon historical region.

In 1707, following King Philip's Nueva Planta decrees a large part of Lower Aragon became the Corregimiento de Alcañiz, a kind of large district. In 1812, as a result of Marshal Louis Gabriel Suchet's territorial division, the Province of Alcañiz (Provincia de Alcañiz) briefly unified the Lower Aragon region during French occupation. Since then, and despite of the strong identity of its inhabitants, this historical region has not been able to achieve the necessary legal recognition for its administrative development.
