A method and an apparatus for measuring a non-contact multiple biosignal are provided. An apparatus for measuring a non-contact multiple biosignal includes: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the apparatus to: radiate first emission light of a first wavelength and second emission light of a second wavelength toward an object to be measured; receive first reflected light of the first wavelength and second reflected light of the second wavelength reflected from the object to be measured; detect first light absorbance for the first reflected light and second light absorbance for the second reflected light; and determine oxygen saturation of the object to be measured based on a difference between the first light absorbance and the second light absorbance.
