The present invention relates to a method for extracting coffee using supercritical nanobubbles, and coffee extracted thereby, and specifically, to a method for extracting coffee capable of extracting coffee by bringing nanobubbles having a high pressure corresponding to a supercritical state into contact with coffee beans, thereby improving an extraction speed of coffee and increasing a concentration of the coffee, and coffee extracted thereby. A method for extracting coffee using supercritical nanobubbles of the present invention includes a bubble water generation step of obtaining bubble water in which nano bubbles are formed, and an extraction step of extracting liquid coffee by applying bubble water to ground coffee beans, in which the bubbles have a diameter of 10 to 200 nm and an internal pressure of 50 to 150 atm.
