The Avro 558 was a British single-engined ultralight biplane built by Avro at Hamble Aerodrome.
The Avro 558 was designed for the 1923 light aircraft trials for single-seaters at Lympne Aerodrome.
The first aircraft was modified with a 698 cc (42.6 in³) Blackburne Tomtit and both had modifications to the landing gear.
