The Avro 720 was an in-development British single-seat interceptor of the 1950s. It was designed and being developed by Avro in competition with the Saunders-Roe-built SR.53. While at least one prototype was partially-constructed, the order for the Avro 720, and quickly thereafter the project entirely, was terminated prior to any aircraft having been completed.

The Avro 720 was intended to have been a high-performance aircraft that would have utilised mixed propulsion to accomplish this, using a rocket engine to achieve quick acceleration and a high top speed while a more compact jet engine would have been used during more mundane cruising flight. The termination of the aircraft had been partially due to its choice in powerplant, Avro having opted to utilise the in-development Armstrong Siddeley Screamer rocket engine, which used liquid oxygen as oxidant and kerosene fuel; major questions were posed over the oxidant's practicality under operational situations.
