OmniWeb is a discontinued web browser developed and marketed by The Omni Group exclusively for Apple's macOS operating system.

After Sun Microsystems bought Lighthouse Design, the Omni Group released the product from version 2.5 onwards.

The Omni Group originally employed its proprietary HTML layout engine that uses standard API NSText components.

Major new features include the use of a custom version of WebKit instead of WebCore,[9] universal binary support, saving to the web archive, support for user-defined style sheets, a "Select Next Link" feature, FTP folder display, ad-blocking improvements, updated localizations, and many other small changes and bug fixes.

John Siracusa, a technology journalist and critic writing for Ars Technica, said, "Finding [this level of functionality] in a proper Mac OS X application from a respected developer with a proven track record is like finding a perfect 1/10,000th scale replica of the Eiffel Tower in a box of crackerjacks.
