The Avro 562 Avis was a two-seat light biplane designed and built by A.V.Roe and Company Limited at Hamble for the 1924 Lympne Light Aeroplane Trials.

The Avis was a single-bay unstaggered biplane with full-span ailerons on both upper and lower wings. It had a fixed landing gear with a tailskid and could be powered by a nose-mounted 32 hp Bristol Cherub II engine or a 35 hp Blackburne Thrush radial piston engine.^[1] It had tandem open cockpits. First flown with the Thrush engine prior to the trials, it was refitted with the Cherub and first flown with this engine by Bert Hinkler at Lympne on 30 September 1924. On the next day, it won the Grosvenor Cup at a speed of 65.87 mph.^[2]

For the 1926 trials, it was re-engined with a 38 hp Blackburne Thrush, being eliminated after a forced landing. In 1927, it was re-engined again with a Bristol Cherub I and passed into private ownership until it was scrapped in 1931.^[3]
