A light tracking sensor and a sunlight tracking system including the same, the light tracking sensor comprises two or more light tunnel devices. One end of the respective light tunnel devices form a common single-point micro-hole acting as an input port for directional light, the other ends of the light tunnel devices act as output ports for directional light and is provided with light-sensing units respectively. A sunlight tracking system is constituted of said light tracking sensor, a differential processing unit, an A/D converting unit, a microprocessor unit, a driving unit and an executive unit driven by the output end of the driving unit. Since one ends of the light tunnel devices form a common single-point micro-hole and the surface around the micro-hole is a curved surface, the sunlight tracking system, compared with the prior art, has a simpler structure, and a higher integration; Meanwhile, when in combination with certain software, a fast, accurate sunlight racking can be achieved, and its tracking precision is less influenced by the outdoor environment.
