Macworld is a web site and monthly computer magazine dedicated to Apple Macintosh products. It is published by Mac Publishing, which is headquartered in San Francisco, California. Published since 1984, the magazine has the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, Life (formerly MacAddict). Macworld was founded by David Bunnell (publisher) and Andrew Fluegelman (editor).

In 1997, the publication was renamed to Macworld, incorporating MacUser (a name reflected subtly on the magazine's Table of Contents page) to reflect the consolidation of the Ziff-Davis-owned MacUser magazine into the International Data Group-owned Macworld within the new Mac Publishing joint venture between the two publishers. In 1999, the combined company also purchased the online publication MacCentral Online, because Macworld didn't have a powerful online news component at the time. In late 2001 International Data Group (IDG) bought out Ziff-Davis' share of Mac Publishing, making it a wholly owned subsidiary of IDG.

The magazine is published in many countries, either by other IDG subsidiaries or by outside publishers who have licensed the brand name and its content. These editions include Australia, Germany (Macwelt), Italy, Spain, Sweden (MacWorld), Turkey, the United Kingdom and Indonesia. Its content is also incorporated into a number of other IDG publications.

The magazine's publisher licenses its name to another IDG subsidiary, IDG World Expo, for the Macworld Conference & Expo, which takes place every January at the Moscone Convention Center in San Francisco.

In additional to publishing a monthly print magazine, Macworld also operates numerous web sites, including Macworld.com, Playlist, MacUser.com, and Mac OS X Hints.
