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.

The United States Department of Veterans Affairs (VA) is a Cabinet-level executive branch department of the federal government charged with providing lifelong healthcare services to eligible military veterans at the 170 VA medical centers and outpatient clinics located throughout the country. Non-healthcare benefits include disability compensation, vocational rehabilitation, education assistance, home loans, and life insurance. The VA also provides burial and memorial benefits to eligible veterans and family members at 135 national cemeteries.
