The Avro 531 Spider was a British fighter aircraft of World War I that did not proceed past the prototype stage. It was a sesquiplane of largely conventional configuration but used Warren truss-type interplane struts, hence the appellation "Spider". In tests, the aircraft demonstrated exceptional performance, handling, and pilot visibility. Unfortunately, by the time it flew, the War Office had already selected the Sopwith Snipe for mass production.

A second, refined version, the 531A was apparently never completed, but some of its components seem to have been used to build a derivative design, the 538. This had standard interplane struts and was intended as a racing aircraft. It was never used for this purpose, however, since it was discovered that it had a faulty wing spar, so the Avro firm used it as a hack instead.
