The invention provides a wavelength division multiplexing filtering optical receiver. The wavelength division multiplexing filtering optical receiver comprises an incidence optical fiber. An optical detection chip is arranged at the end opposite to the incidence optical fiber. A diverging lens, a filtering piece and a focusing lens are sequentially arranged between the incidence optical fiber and the optical detection chip. Light beams, with different wave lengths, emitted by the incidence optical fiber are emitted to the filtering piece in parallel after passing through the diverging lens and are focused on the optical detection chip after passing through the filtering piece. The wavelength division multiplexing filtering optical receiver filters the light beams with different wavelengths at the light receiving end and is wide in application range.
