The Centurion is the tallest known individual Eucalyptus regnans tree in the world, thus making E. regnans the 2nd tallest tree species in the world after the Coast Redwood. The tallest known Coast Douglas-fir is now listed at 99.7m tall and comes a close third. Centurion is also the tallest known angiosperm in the world. The tree is located in southern Tasmania, Australia and was measured by climber deployed tapeline at 99.6 metres (327 ft) tall in 2008. A more recent measurement in January 2014 showed the tree had grown to 99.82m  Discovered in August 2008 by employees of Forestry Tasmania while analysing the data collected by LiDAR system used in mapping and assessment of state forest resources.
The diameter of Centurion is 4.05 metres, and its girth exceeds 12 metres. Its volume has been estimated at 268 cubic metres. The name "Centurion" was saved for the hundredth noble tree to be discovered by Forestry Tasmania and coincided with the height of the tree. Named after centurions (Roman officers), the root of the name contains centum, which in Latin means "one hundred". Centurion is alternately known as "the Bradman" as the height of the tree, 99.82 metres, is close to the test run average of the legendary Australian cricketer Donald Bradman.
The tree is located in a small patch of very old forest surrounded by secondary forest and has survived logging and forest fires by lucky coincidence. Near Centurion grows two another giant trees; the 86.5 metre tall E. regnans named Triarius and 'The Prefect' which has an impressive girth of 19m.
