Palm Desktop is a personal information manager computer program for Microsoft Windows or Mac OS/Mac OS X and can be used alone or in combination with a Palm OS personal digital assistant.

The original Macintosh and Windows versions were similar, until 3COM purchased the Claris Organizer, a Mac-only product, from Claris and rebranded it as Palm Desktop 2. Interestingly, the four modules of Claris Organizer had influenced some of the original Palm developers, who were familiar with it from earlier work on the Macintosh.

Palm Desktop contains four main modules which correspond to the four main modules of the original Palm Pilot:

Contacts, analogous to index cards in a rolodex or address book

Calendar information as discrete or repeating appointments

Tasks, sortable by priority, date or category in task lists

Notes, for reference materials, memoranda or journal entries

Palm Desktop ships with all current Palm devices, and it can synchronize with a variety of devices using Palm's HotSync software. It is also available as a free download and can be used as a standalone application on personal computers. The Macintosh version has a much more sophisticated interface and many more options inherited from its history as Claris Organizer, including extensive printing capabilities for mailing labels and printed pages in various sizes of paper organizer.

Desktop 6.2, a beta version for Windows Vista, was released in July, 2007. Although "Not recommended for other Windows versions such as Windows XP or Windows 2000", 6.2 has been seen to run with no problems on Windows XP SP2.

Linux support

Palm does not provide a version of the software for Linux operating system, nor do they officially support the ones developed by third parties such as J-Pilot, Gnome-Pilot.
