Mark Edward Green (born November 8, 1964) is an American politician, physician, and retired U.S. Army officer who has served as the U.S. representative for Tennessee's 7th congressional district since 2019.

Green first entered state politics in 2012 by defeating Democratic incumbent Tim Barnes for a seat in the Tennessee Senate.

In 1986, Green graduated from the United States Military Academy, where he earned a Bachelor of Science in quantitative business management.

Following a traumatic event in which a team of surgeons and critical care doctors saved his father's life, Green requested that the Army send him to medical school.

Green founded and served as chief executive officer of Align MD, a hospital emergency department management staffing company.

[18][19] He led the charge in Tennessee for automated technology in auto manufacturing, speaking at national conferences on the topic.

[25] At a September 2016 Tea Party gathering in Chattanooga, Tennessee, Green said, "If you polled the psychiatrists, they're going to tell you that transgender is a disease.

"[26] He also supported a state law that limited access to public restrooms for transgender people to those matching their legal sex, not their gender identity, and told internet radio talk show host CJ Porter that he viewed his support of that law as part of his duty as a state senator to "crush evil".

[26][27] Green also said that if school districts "want to have a bathroom that's separate for all of the, you know, guys or gals with question marks" but were concerned the "AFL-CIO is going to sue you, well, I got your back."

Green became the Republican nominee for the 2018 U.S. House of Representatives election in Tennessee's 7th congressional district after running unopposed for the nomination.

[38] In a closed-door GOP meeting in 2024, Green called Secretary of Homeland Security Alejandro Mayorkas "a reptile with no balls.

[40] On July 29, 2024, Green was announced as one of seven Republican members of a bipartisan task force investigating the attempted assassination of Donald Trump.

During a town hall meeting, he acknowledged that carbon dioxide levels are increasing but questioned whether they are causing global warming.

[49] Green rejects the theory of evolution, which is consensus in biology; in a 2015 lecture he used creationist reasoning such as "irreducible complexity".

[51] In December 2020, Green was one of 126 Republican members of the House of Representatives to sign an amicus brief in support of Texas v. Pennsylvania, a lawsuit filed at the United States Supreme Court contesting the results of the 2020 presidential election, in which Joe Biden prevailed over incumbent Donald Trump.

[52] The Supreme Court declined to hear the case on the basis that Texas lacked standing under Article III of the Constitution to challenge the results of an election held by another state.

[53][54][55] In 2018, as a congressman-elect, Green said at a constituent meeting, "there is some concern that the rise in autism is the result of the preservatives that are in our vaccines", a claim that has been repeatedly debunked by scientific studies and rejected by medical organizations such as the American Academy of Pediatrics.

[58][59] The PACT ACT which expanded VA benefits to veterans exposed to toxic chemicals during their military service, received a "nay" from Green.

For most of his tenure in the state senate, he lived in Ashland City, in Cheatham County, south of Clarksville and west of Nashville.

[65] In a text message circulated among House Republicans, his wife later accused him of having an affair with a younger woman working as a political reporter for Axios.
