The ST Book (also written as STBook) is a notebook-sized laptop released in October 1991 by Atari Corporation.{{cite journal | date=October 29, 1991 | url=https://link.gale.com/apps/doc/A11504037/GPS?sid=wikipedia | title=Atari shows off STBook | work=Computergram International | publisher=GlobalData | via=Gale}} It is based on the Atari STE. The ST Book is more portable than the previous Atari portable, the STacy, but it sacrifices several features in order to achieve this: notably the backlight, and internal floppy disc drive.{{Cite web |last=Beschizza |first=Rob |date=2024-10-25 |title=Atari ST Book laptop among the rarest treasures of the 16-bit era |url=https://boingboing.net/2024/10/25/atari-st-book-laptop-among-the-rarest-treasures-of-the-16-bit-era.html |access-date=2025-02-18 |website=Boing Boing |language=en-US}}{{Cite web |date=2015-04-17 |title=AEX - The most comprehensive exploration of Atari online |url=https://web.archive.org/web/20150417093224/http://ftp.pigwa.net/stuff/mirror/www.atari-explorer.com/stbook.html |access-date=2025-02-18 |website=web.archive.org}}

The screen is highly reflective. It supports the 640×400 1-bit mono mode only without an external video port. It gained some popularity as being the most utterly portable full-featured computer of the day (slim, light, quiet, reliable, and with a long battery life, even by modern standards for all 5).

The ST Book is shipped with a modified version of TOS 2.06.
