The Avro 548 was a civil trainer aircraft built in Britain after World War I.

Its design was based extensively on Avro's 504 military aircraft, but it had an inline engine and a third seat.

In practice, these aircraft were usually customised for their buyers and most differed from each other in equipment and detail; some were retrofitted war-surplus 504s.

A revised version, the 548A resulted when fitted with an ADC Airdisco engine, a development of the Renault which gave 120 hp (90 kW).

[1] Plans for a version with an enclosed cabin, designated 553 were never brought to fruition.
