The invention discloses a dispersed copper composite material and a preparation method thereof, belonging to the technical field of dispersed copper processing. The dispersed copper composite material is composed of the following components in percentage by mass: 0.24-3.74% of Al2O3, 0.03-1.27% of Y2O3 and the balance of Cu and unavoidable impurities. The dispersed copper composite material is prepared from Cu2O powder and Cu-Al-Y alloy powder through the steps of mixing, pressing, sintering and internal oxidation, extruding and forging; the composite material has the high strength of 500Pa or above and the high conductivity of 80% IACS or above and overcomes the defect that the high strength and high conductivity of other composite materials cannot simultaneously exist; and meanwhile the composite material is favorable in softening resistance, high in high-temperature strength and good in plasticity, and the softening temperature is 800 DEG C or higher.
