Mountain Home National Cemetery is a United States National Cemetery located at Mountain Home, within Johnson City in Washington County, Tennessee. Administered by the United States Department of Veterans Affairs, it encompasses, and as of 2018, had over 17,000 interments.
On the grounds of the Mountain Home Veterans Administration Center, the cemetery was established in 1903 as part of the National Home for Disabled Volunteer Soldiers, a federal old soldiers' home. The cemetery features over 14,000 graves highlighted by a monument to Congressman Walter Preston Brownlow, who petitioned the government and worked tirelessly to have the veteran's center created. It officially became a National Cemetery in 1973, and has primarily the interments of veterans who died while under care at the facility.
