The Double Racer (German: Rennzweier) is a race car manufactured by the Nesselsdorfer Wagenbau-Fabriksgesellschaft (NW), now Tatra, in 1900. It is sometimes also called First Racing, 12 HP, or Race Car (German: Rennwagen). It was commissioned by Baron Theodor von Liebieg. Hans Ledwinka, the man behind the famous rear-engined Tatras, and at the time only 20 years old, helped in the production of the car. The car was designed and built in a five week period in April and May 1900. The Rennzweier was the first car designed specifically for racing to be built in Central Europe.

In 1994, a 2 commemorative stamp featuring the Rennzweier, designed by Bedřich Housa, was issued.
