Any of a group of fibrous proteins (including keratin fibres, neurofilaments, desmin, and vimentin) that make up part of the cytoskeleton of most eukaryotic cells; so named because, at about \(\pu{10 nm}\) diameter, they are intermediate in thickness between actin filaments and microtubules.

Note: Most types of intermediate filaments are cytoplasmic, but one type, the lamins, is nuclear.
