Rancilio is an espresso machine manufacturer, founded in 1927 by Roberto Rancilio in Parabiago, Milan, Italy. Rancilio would become best known for its innovative distribution networks, effective use of industrial design and reputable reliability.

Rancilio's earliest well-known machine was 'La Regina' – a vertical boiler machine, similar to the original Bezzera and Victoria Arduino devices in function and gilded 'Belle Epoque' styling.
