Portaro is an automotive brand focused on producing off-road vehicles, particularly 4×4 SUVs and light trucks. Originating from Portugal, the company was a collaborative project involving several entities, including the Romanian ARO and the Portuguese automotive manufacturer, MV Mecânica. Operating mainly during the late 1970s to the early 1990s, Portaro had a strong presence in its home country of Portugal and expanded its market to various European countries. The company, however, gradually faded in prominence and ceased its operations.
