Leo Breiman (January 27, 1928 – July 5, 2005) was a statistician at the University of California, Berkeley. He was the recipient of numerous honors and awards,^{[citation needed]} and was a member of the United States National Academy of Sciences.

Breiman's work helped to bridge the gap between statistics and computer science, particularly in the field of machine learning. His most important contributions were his work on classification and regression trees and ensembles of trees fit to bootstrap samples. Bootstrap aggregation was given the name bagging by Breiman. Another of Breiman's ensemble approaches is the random forest.
