The invention provides a high-speed maglev train speed measurement sensor and a maglev train, and relates to the technical field of maglev train speed measurement. The high-speed maglev train speed measurement sensor comprises a sensor body capable of being installed on a maglev train, at least one probe coil installed on the sensor body and parallel to a long stator of a maglev track, and a sampling processing circuit. The probe coil is in a planar spiral shape and is loaded with an alternating excitation signal; the sampling processing circuit can process the alternating current signal of the probe coil into a digital signal indicating the impedance change of the probe coil. The high-speed maglev train speed measurement sensor provided by the invention can perform high-precision real-time speed measurement on a maglev train, and is low in cost.
