Austro-Daimler was an Austrian auto-maker company, from 1899 until 1934, presumably connected with Daimler Motoren Gesellschaft of Germany.

A water-cooled six-cylinder Austro-Daimler engine was enlarged and improved by Frank Bernard Halford, producing the 230 hp (170 kW) Beardmore-Halford-Pullinger (BHP). This engine was further developed by Siddeley-Deasy as the Puma. This work was done with Arrol-Johnston in Dumfries.
