The Ordem dos Engenheiros (OE, English: Order of Engineers) is the regulatory and licensing body for the engineering profession in Portugal. It is headquartered in Lisbon, and has several regional branches in other Portuguese cities. The OE was established by law in 1936. It succeeded the Portuguese Association of Civil Engineers, founded nearly 70 years earlier. The OE is a member of many international engineering organizations, including general engineering ones (e.g. FEANI) and those for specific engineering disciplines (e.g. ECCE, EUREL, EFCE).
