The invention belongs to the technical field of optical antennas, and in particular relates to a multi-channel optical receiving antenna. The receiving antenna provided by the invention comprises a first lens group, a second lens group and a third lens group; the first lens group is composed of a meniscus lens with negative focal power; the second lens group is composed of a doublet lens with positive focal power and two meniscus lenses with positive focal power; and the third lens group is composed of a meniscus lens with negative focal power. The multi-channel optical receiving antenna provided by the invention has the advantages of large field angle, high gain and large receiving power and signal to noise ratio; by using the multi-channel optical receiving antenna, the separation of optical signals of different channels in indoor visible light communication can be achieved, the signal crosstalk can be greatly reduced; and the high-speed and stable communication requirement can be met.
