David Jonathon Shulkin is an American physician and former government official. In 2017, Shulkin became the ninth United States Secretary of Veterans Affairs and served under President Donald Trump. He was the Under Secretary of Veterans Affairs for Health from 2015 until 2017, appointed by President Barack Obama. On March 28, 2018, President Trump dismissed Shulkin from his position by tweet, and announced that Physician to the President Ronny Jackson would be nominated as Shulkin's successor, although Jackson's nomination was withdrawn on April 26, 2018, after allegations surfaced of misconduct and mismanagement while serving in the White House. He was succeeded by Under Secretary of Defense Robert Wilkie.

The United States secretary of veterans affairs is the head of the United States Department of Veterans Affairs, the department concerned with veterans' benefits, health care, and national veterans' memorials and cemeteries. The secretary is a member of the Cabinet and second to last at sixteenth in the line of succession to the presidency. Until the appointment of David Shulkin in 2017, all appointees and acting appointees to the post were United States military veterans, but that is not a requirement to fill the position.
