Mark Edward Green (born November 8, 1964) is an American politician, physician, and retired U.S. Army surgeon who served as the U.S. representative for Tennessee's 7th congressional district from 2019 until his resignation in 2025. A member of the Republican Party, Green chaired the Committee on Homeland Security from 2023 to 2025. Before his election to Congress, he served in the Tennessee Senate, representing the 22nd district from 2013 to 2018.

After graduating from West Point, Green was an infantry officer. He then graduated from Boonshoft School of Medicine at Wright State University and became a flight surgeon, serving tours of duty in the War in Afghanistan and Iraq War. He wrote a book about his experience in Operation Red Dawn, in which Saddam Hussein was captured. After retiring from the military in 2006, Green became the CEO of a hospital emergency department staffing company.

Green first entered state politics in 2012 by defeating the Democratic incumbent Tim Barnes for a seat in the Tennessee Senate. In 2017, President Donald Trump nominated Green to serve as the United States secretary of the Army, but when comments Green had made about the LGBT community were revealed, he withdrew his nomination. When U.S. representative Marsha Blackburn announced her candidacy for the United States Senate in 2018, Green announced his candidacy to succeed her, and was elected in November of that year. He was re-elected in 2020 and 2022. In October 2023, he was a candidate for Speaker of the House of Representatives, but withdrew from the race on October 24.

On June 9, 2025, Green announced that he would be resigning after the passage of the One Big Beautiful Bill Act to take a job in the private sector. His last day in office was on July 20, 2025.
