Oestridae (also called botfly or bot fly) is a family of Oestroidea. It is one of several families of hairy flies whose larvae live as parasites within the bodies of mammals, such as the Desert Woodrat. There are approximately 150 known species worldwide.

Only one bot fly species attacks humans, the Dermatobia hominis. For many years the deer botfly was cited as the fastest flying insect in the Guinness Book of World Records, but the claim has been refuted and is no longer considered probable.
