American Typewriter is a slab serif typeface created in 1974 by Joel Kaden and Tony Stan for International Typeface Corporation. It is based on the slab serif style of typewriters; however, unlike most true typewriter typefaces, it is a proportional design: the characters do not all have the same width. American Typewriter is often used to suggest an old-fashioned or industrial image. It was originally released in cold type (photocomposition) before being released digitally. Like many ITC typefaces, it has a range of four weights from light to bold (with matching italics) and separate condensed styles. Some releases do not have italics.

American Typewriter was by no means the first typeface to imitate typewriting. Foundry catalogs of the late nineteenth century were already offering them, and press manufacturers even made press-size ribbons so that letters looking as if they had been typed could be produced wholesale. The different types made it very popular and well-seen among advertisements and different branding companies.

In the original release, the A faces are identical to the regular ones, except for alternate versions of the following characters: &, $, R, e. This typeface was given a more legible look by creating round edges and giving enough space between each letter.

The famous I Love New York (I ♥ NY) logo is set in a slightly-modified version of this typeface.

From the 1983–84 season to the 1988–89 season, MotorWeek used the typeface for road tests, as well as the closing credits.

CBS sitcom Young Sheldon uses it in its opening and closing credits, as well as its logo.

Chuck Lorre used this typeface in his vanity cards.

The U.S. TV series The Office uses the typeface as its main logo, as does the U.S. TV series Psych (using the bold variant).
