An ultra-wideband (UWB) localization method, a UWB localization device, and a UWB localization system are provided. The UWB method includes: determining whether or not a plurality of UWB hardware measurement deviations are calibrated; determining, when the UWB hardware measurement deviations are calibrated, whether or not a plurality of anchor coordinates of anchors are automatically measured; obtaining, when the anchor coordinates of the anchors are automatically measured, a plurality of measurement distances between each of the anchors and a tag, respectively, and deducting the UWB hardware measurement deviations from the measurement distances, respectively; and calculating a tag coordinate of the tag according to the measurement distances from which the UWB hardware measurement deviations are deducted.
