The invention provides a signal waveform-based space neutron discrimination device, which is used for solving the problem that neutrons cannot be effectively discriminated from space charged particles in the prior art. Comprising a front 3He neutron counter, a high-voltage power supply, a low-voltage power supply, a front collecting electrode charge amplifier, a main amplifier, a discrimination circuit, a shaping and shaping circuit and an output circuit, the front collecting electrode charge amplifier is used for collecting charges of the 3He neutron counter, amplifying and converting the charges into voltage, and sending a voltage signal to the main amplifier; the main amplifier collects a voltage signal of the charge amplifier before receiving the voltage signal, filters the voltage signal, improves the signal-to-noise ratio, and sends the filtered voltage signal to the discrimination circuit; the discrimination circuit converts the analog signal output by the main amplifier into a digital logic pulse outp
