Ronald Lee Gilman (born October 16, 1942 in Memphis, Tennessee) is a Senior United States circuit judge of the United States Court of Appeals for the Sixth Circuit.

Gilman attended the Massachusetts Institute of Technology in 1964 and received a Scientiae Baccalaureus degree in Economics.

[1][2] Gilman was nominated to the United States Court of Appeals for the Sixth Circuit by President Bill Clinton on July 16, 1997 after the seat had been vacated by Judge Herbert Theodore Milburn.

[2] In ACLU v. NSA, the Court of Appeals for the Sixth Circuit decided to vacate the District Court's decision that the extrajudicial electronic intercepts of the National Security Agency, where one party is within the U.S. and the other is outside, violated the law.

Judge Ronald Gilman wrote a long dissent, in which he argued that the plaintiffs did have standing, and that the Terrorist Surveillance Program as originally implemented violated the FISA.
