The invention belongs to the technical field, and discloses a quick-response thermocouple probe. The quick-response thermocouple probe is formed by thermocouple wire poles, a probe pole, a corundum pipe, a thermocouple measuring contact and thermocouple wires, wherein the thermocouple wire poles support the thermocouple wires; the thermocouple wires are straightened through the thermocouple wire poles, and are horizontal-line shaped; the thermocouple measuring contact is located at the middle part; and facing toward the air-flow direction, the exposed thermocouple wires and the thermocouple wire poles are in II-shaped, and the shape can guarantee that the thermocouple fully contacts the flow field and is convenient for exchanging the thermocouple wires. The quick-response thermocouple probe is generally suitable for K-type, T-type and J-type of thermocouples. Compared with a traditional thermocouple probe, the thermocouple probe can select a thermocouple with very small thermal inertia; the thermocouple wires can be fixed in the flow field to be detected through the thermocouple wire poles; the thermocouple probe can measure the high frequency pulsation air-flow temperature; and the thermocouple wires can maintain intensity and rigidity under the high speed air-flow impact, and are not easy to be bent and deformed.
