Seixal is situated on the peninsula of Setúbal and is part of the metropolitan area of Lisbon. The municipality is bordered to the east by the municipality of [[Barreiro Municipality|Barreiro]], south by [[Sesimbra]], west by [[Almada]] (with which it has a strong affinity) and the north by the [[Tagus]] estuary, through which connects to Lisbon.

The Bay of Seixal is part of the Tagus River Estuary, that is fed by several rivers and confluents that extend to the sea; classified as a ''Reserva Ecológica Nacional'' (''National Ecological Reserve''), the bay and small tributaries are part of one of the most important humid zones in Portugal, supporting an elevated biodiversity and exceptional landscape.<ref name="CMTerritoria">{{citation |url=http://www.cm-seixal.pt/historia |title=Território |location=Seixal, Portugal |language=pt |year=2015 |access-date=11 October 2015 |editor=Câmara Municipal |publisher=Câmara Municipal de Seixal}}</ref>

Although the municipal population continued to grow with development, after the 1970s there was a boom in the population, due to improvements in accessibility and mobility, principally due to public transport, its location to Lisbon and installation of economic activities within the territory.<ref name=CMTerritoria/> This growth transformed, in a short time, from a territory predominantly rural into an urban municipality, consisting of agglomerations of large dimensions focusing on various establishments and social centres.<ref name=CMTerritoria/> This growth resulted in the 1993 elevation of Seixal and Amora into cities, and the establishment of Corroios into the status of town.<ref name=CMTerritoria/>
