ARO (short for Auto Romania) was a Romanian off-road vehicle manufacturer located in Câmpulung-Muscel. The first ARO vehicles were produced in 1957, and the last in 2003. For a short while, Daihatsu-powered AROs were sold in Spain and produced in Portugal under the brands Hisparo and Portaro, respectively. In Italy, Volkswagen-powered AROs were produced by ARO-Ciemme and sold under the ACM brand.

Low volume production of ARO vehicles has restarted under the aegis of a Czech company called Auto Max Czech (AMC).
