Chicago is a sans-serif font designed by Susan Kare for Apple Computer. It was used in the Macintosh operating system user interface between 1984 and 1997 and was an important part of Apple's brand identity. It is also used in the iPod user interface. While initially a bitmap font, Apple commissioned the type foundry Bigelow & Holmes to create a TrueType version, as the OS' capabilities improved. The typeface is, of course, named after the United States city of Chicago, Illinois.

According to Susan Kare, Chicago was the first font to be developed for the Macintosh. Before the team settled on the familiar "world cities" naming convention for the fonts, it was called Elefont (Elefont is also the name of a bold semi-serif typeface designed by Bob McGrath in 1978). The first bitmap version included only a 12 pt version. This font, with only very minor changes to spacing, was used for menus, dialogs, window titles and text labels in up to and including version 7.6 of the system. The TrueType version looked identical to the original bitmap typeface at lower sizes, but scaled better to greater sizes. One of Chicago's major features was that it could be made 'grey' (to indicate a disabled menu item) by removing every other pixel (since actual grey type was impossible on a black-and-white monitor) and remain legible.

German versions of System 7.x had a different rendering of Chicago. The "w" had two dips instead of one at the end of the letter, and the "I" (capital "i") appeared more like a column than a vertical line. A mix of this and the original Chicago is used in the iPod.

In Mac OS 8, Charcoal replaced Chicago as the default system font. Chicago continued to be distributed as a standard component of the system, and Apple even urged developers to keep designing user interfaces for the Chicago typeface, since the new alternate fonts used the Chicago metrics as a foundation.

Chicago was also used in Apple marketing materials. It was also common to find this font in early amateur desktop publishing productions, since it was available as part of the system. While Apple gravitated away from Chicago following the adoption of Charcoal as part of the platinum theme in Mac OS, it was later revived in the user interface for the iPod music player, where legibility on a black-and-white screen became once again an asset.

Chicago is a registered trademark ("typeface fonts recorded on computer software"), belonging to Apple since August 1996.

It was heavily used by The Designers republic , especially on many IDM music covers.
