Plectreuridae, sometimes called plectreurid spiders, are a small spider family confined to the Southwestern United States, Mexico, and the Caribbean. Only two living genera are known - the nominate genus Plectreurys and Kibramoa. In the past, the family was more widespread, with the Jurassic genus Eoplectreurys known from China, the Eocene Palaeoplectreurys baltica from Baltic amber and the Miocene Plectreurys pittfieldi from Dominican amber.
