The Arrows A1 was the car with which the Arrows Formula One team competed in the 1978 and 1979 Formula One seasons. It was a replacement for the Arrows FA1, which the team had been forced to withdraw after a legal protest from the Shadow team on the grounds that it was too similar to their own design; the result of the Arrows team being formed earlier in the year from a splinter group of disgruntled Shadow employees. The team must have anticipated that they would lose the legal case brought by Shadow, as the A1 was ready for a press launch three days after the court case ended. A B-spec version of the chassis was used in 1979, before the introduction of the radical, but unsuccessful, A2.

The A1 also competed in the 1978, 1979 and 1980 British Formula One Series seasons.
