Aljucén is a municipality in the province of Badajoz, in the Extremadura region of western Spain. It is a small rural settlement in a sparsely populated part of the country, near the border with Portugal.
The municipality had a population of 247 inhabitants according to the 2006 census carried out by the Instituto Nacional de Estadística (INE), Spain's national statistics institute. This figure reflects the modest size typical of many villages in the Extremadura countryside.
Aljucén lies within the province of Badajoz, one of the two provinces that make up the autonomous community of Extremadura, the other being Cáceres. The region is known for its dry, open landscapes and historic towns, though Aljucén itself remains a small local administrative unit centred on its own village settlement.
