A coherent optical receiver module is disclosed. The module includes a housing, an optical fiber group, a first optical element, and a second optical element. The housing stores a first optical component disposed on an optical path of a local beam and a second optical component disposed on an optical path of a signal beam. The optical fiber group includes a first optical fiber optically coupled to the first optical component and a second optical fiber optically coupled to the second optical component. The first optical element has a first lens disposed on the optical path of the local beam, and transmits the signal beam and the local beam. The second optical element has a second lens disposed on the optical path of the signal beam, and transmits the signal beam and the local beam. The first optical element and the second optical element are placed side by side between the optical fiber group and one end surface of the housing.
