Tallest buildings
This list ranks the top-ten tallest buildings in Knoxville, based on standard height measurement. This includes spires and architectural details but does not include antenna masts. The "Year" column indicates the year in which a building was completed.

The University of Tennessee, Knoxville's campus contains several tall buildings. While sources on their height are difficult to find, sources that list the number of stories indicate that, if their heights were known, a few of them may be among Knoxville's tallest ten buildings (as in the table above). As of January 28, 2024, the tallest buildings on campus as measured by number of stories (given in parentheses for each) &mdash; and that have at least as many stories as the smallest building listed on the table above &mdash; were the McClung Tower (17), Laurel Residence Hall (15), Carrick Hall North (14), Dabney-Buehler Hall (14), Andy Holt Tower (13), Volunteer Hall (12), Hess Hall (11), 11th Street Parking Garage (10), Frank G Clement Hall (10), Massey Hall (10), Stokely Management Center (10), and the West Skybox Addition (10). Interestingly, Carrick Hall South is listed as having 0 stories, despite having connecting stories with Carrick Hall North.

Demolished buildings
The smokestack of the University of Tennessee, Knoxville's steam plant was one of Knoxville's tallest buildings from its completion in 1966 until its demolition in 2016. Standing at 300 feet tall (which is taller than the Sunsphere), it was the tallest building on campus at the time of its completion. The coal-powered steam plant was converted to a natural gas plant, which included the smokestack being demolished; this process started in March 2014 and concluded in January 2016. A time-lapse video of the entire demolition process was recorded and posted online.
