James G. Moran (May 2, 1870 – April 12, 1941) was an American politician who served as President of the Massachusetts Senate from 1935 to 1936.

He studied civil engineering at the Massachusetts Institute of Technology, but left after a year due to the death of his father.

He then worked for many years as a signal tower operator for the New York, New Haven and Hartford Railroad.

The Democrats wanted to persuade a Republican to run against incumbent Erland F. Fish for the Senate presidency in exchange for an equal division of committee chairmanships.

On the eighth ballot, Republican William A. Davenport switched sides and Moran was elected with 20 votes to Fish's 13 and Samuel H. Wragg's 5.
