The Estremadura Limestone Massif (Portuguese: {{lang|pt|Maciço Calcário Estremenho}}) is a massif located in central west Portugal. Approximately half of the massif is located within the Serras de Aire e Candeeiros Natural Park. The massif has an elongated NE-SW direction and englobes the municipalities of Batalha and Ourém in the north and northeast; Torres Novas and Alcanena in the east and southeast; Rio Maior in the south; and Alcobaça in the west.{{cite journal |last1=Azerêdo |first1=Ana C. |title=Formal lithostratigraphy of the Lower and Middle Jurassic from the Maciço Calcário Estremenho (Lusitanian Basin) |journal=Comunicações Geológicas |date=2007 |pages=29–51 |url=https://www.lneg.pt/wp-content/uploads/2020/03/ComunGeol_V94_N1_Article_2.pdf}}{{cite journal |last1=Machado |first1=S. |last2=Mergulhão |first2=L. |last3=Martins |first3=O. |last4=Carvalho |first4=J.M.F |title=Geological heritage assessment in mining areas of serra de aire and candeeiros natural park |journal=Comunicações Geológicas |date=2014 |url=https://www.researchgate.net/publication/311262226_Geological_heritage_assessment_in_mining_areas_of_serra_de_aire_and_candeeiros_natural_park |issn=0873-948X}}{{cite journal |last1=M.
