Abram Bergen (often misreported with first name Abraham or last name Berger; March 1836 – February 5, 1906)[1][2] was an American lawyer who served as a justice of the New Mexico Territorial Supreme Court from 1869 to 1870.

He earned a bachelor's degree from Illinois College, and attended Harvard Law School, but did not graduate.

[4] As a young attorney, he witnessed the "Almanac trial", in which Abraham Lincoln, as counsel for criminal defendant Duff Armstrong, won his case by using an almanac to demonstrate that the prosecution witness was lying about there being a full moon enabling him to see clearly on the night of the crime.

[6][7] On April 13, 1869, it was reported that Bergen was among the nominees sent to Congress by the administration of President Ulysses S. Grant,[8] having been nominated for a seat on the New Mexico territorial supreme court.

His death was caused by pneumonia and heart trouble, and it was reported that he had been ailing about three weeks, but was seriously sick for only a few days.
