De inch (afkorting: in of ") is een lengte-eenheid in de (Britse) imperiale en Verenigde Staten gebruikelijke meetsystemen nu formeel gelijk aan 1/36 yard, maar wordt meestal begrepen als 1/12 van een voet. Afgeleid van de Romeinse uncia ("twaalfde"), wordt inch soms ook gebruikt om verwante eenheden in andere meetsystemen te vertalen, meestal begrepen als afgeleid van de breedte van de menselijke duim.
