Michael Thomas "Mike" Flynn (born December 1958) is a retired United States Army lieutenant general who served as the director of the Defense Intelligence Agency, commander of the Joint Functional Component Command for Intelligence, Surveillance and Reconnaissance, and chair of the Military Intelligence Board from July 24, 2012, to August 2, 2014. Prior to that, he served as Assistant Director of National Intelligence. 

Flynn co-authored a report in January 2010 through the Center for a New American Security entitled Fixing Intel: A Blueprint for Making Intelligence Relevant in Afghanistan, which criticized the intelligence community for lacking an understanding of the human-socio context of the battlefield in Afghanistan.

Flynn's military career was primarily operational, with numerous combat arms, conventional and special operations senior intelligence assignments. He also served as the senior intelligence officer for the Joint Special Operations Command. Flynn is a published author, with articles appearing in Small Wars Journal, Military Review, Joint Forces Quarterly and other military and intelligence publications.

In May 2016, he emerged as one of several leading possibilities to be the vice presidential running mate for Republican nominee. Flynn was not chosen as Trump's running mate; the vice presidential pick was ultimately Indiana Governor Mike Pence. At the 2016 Republican National Convention in Cleveland, Ohio, Flynn delivered what the Los Angeles Times called a "fiery speech".

On November 18, 2016, the Transition announced via press release that President-elect  had named General Flynn his National Security Advisor
