Complutum (ISSN 1131-6993, ISSN-e 1988-2327), which was published annually up to issue 18 and biannually after that, was founded in 1991 by Professor Martín Almagro Gorbea. The publication disseminates high quality archaeological research to the national and international community in all fields, with a particular focus on the Prehistory of the Iberian Peninsula. 

It predominantly deals with theoretical, methodological and interdisciplinary works, in addition to summaries of new areas of research on reports concerning archaeological sites, museum collections or exceptional archaeological pieces. The journal accepts articles written from different theoretical positions and supports gender equality in the scientific field. One of the two annual volumes presents articles on a variety of topics whilst the other generally focuses on one topic, with one or several editors responsible for its content. Both also offer a review section and scientific news.
