Migidae, also known as tree trapdoor spiders, is a family of spiders with about 100 species in eleven genera.

They are small to large spiders with little to no hair and build burrows with a trapdoor. Some species live in tree fern stems.

They have a Gondwanan distribution, found almost exclusively on the Southern Hemisphere, occurring in South America, Africa, Madagascar, Australia, New Zealand and New Caledonia.
