The invention discloses a method and device for predicting the octane number of gasoline, and relates to the technical field of oil and gas data processing and computers.The method comprises the steps that content data of component mapping molecules of a to-be-processed gasoline fraction is determined according to chromatographic analysis data of the to-be-processed gasoline fraction; classifying the component mapping molecules into a first type of mapping molecules with known octane number or a second type of mapping molecules with unknown octane number; when the component mapping molecules of the gasoline fraction to be treated comprise a second type of mapping molecules, virtualizing the second type of mapping molecules into lumped molecules corresponding to the lumped component type according to the molecular carbon number and the family composition type of the second type of mapping molecules; determining the content data of lumped molecules according to the content data of the second type of mapping mol
