Aaron Cecil Snyder (September 14, 1907 – June 29, 1959) was an American lawyer who served as a prosecutor and judge in Puerto Rico.
After attending Baltimore City College and Johns Hopkins University as an undergraduate, he graduated from Harvard Law School in 1930.
In 1942, President Franklin D. Roosevelt appointed Snyder as an Associate Justice of the Supreme Court of Puerto Rico.
As Associate Justice, he appeared before the United States House of Representatives' Committee on Public Lands in 1950 in support of a bill allowing Puerto Rico to draft a local constitution.
Four years later, in July 1957, after most of Puerto Rico's legal establishment had lost confidence in Snyder's leadership as Chief Justice, he resigned from the court effective September 15, 1957.
