In publishing, a callout or call-out is a short string of text connected by a line, arrow, or similar graphic to a feature of an illustration or technical drawing and giving information about that feature. The term is also used to describe a short piece of text set in larger type than the rest of the page and intended to attract attention. In documents that require translation, a neutral callout is often used. By using numbers or letters as callouts in combination with an image caption, translation becomes more efficient, as the same graphic can be used in all languages.

A similar device in word processing is a special text box with or without a small "tail" that can be pointed to different locations on a document.^[1]

In the utility industry, a callout is an instruction to report for emergency or special work at an unusual time or place.^[2]
