Delicatessen is a term meaning "delicacies" or "fine foods". The word entered English via German, with the old German spelling (modern German: Delikatessen), plural of Delikatesse "delicacy", ultimately from Latin delicatus.

The term delicatessen has a secondary meaning in some countries, referring to stores that sell delicatessen; the word delicatessen thus also is used as a shortened term for delicatessen store. Sometimes this is further shorted to the informal term deli.
