Edward A. Counihan Jr. (1882 – February 1, 1961)[1] was a justice of the Massachusetts Supreme Judicial Court from 1949 to 1960.

Born in Cambridge, Massachusetts,[1] and raised in Dorchester, Counihan attended Cambridge Latin School, and received an undergraduate degree from Harvard College in 1904, followed by a law degree from Harvard Law School in 1906.

[2] Counihan and Dever were friends from childhood,[2] and Counihan's later classmates included Franklin D. Roosevelt at Harvard College, and Felix Frankfurter at Harvard Law School.

[1] Counihan was "active in city government" in Cambridge,[1] and chaired the committee of arrangements of a charitable gala in 1909.

On March 23, 1921, Governor Channing H. Cox named Counihan to a seat on the District Court of East Cambridge,[4] where Counihan remained for 28 years, before being named to the state supreme court in 1949.
