Microsoft Office Mobile是由Microsoft为Windows Phone、iOS、Android等移动设备操作系统开发的一套办公套件。该套件由Word Mobile、Excel Mobile、PowerPoint Mobile、OneNote Mobile以及Outlook Mobile组成。它亦都与桌面版本相兼容。在2000年4月随Pocket PC 2000操作系统首次发行时，Office Mobile被称为“Pocket Office”，在此之后此套件进行了数次更新。

Microsoft Office Mobile is a freeware (except for editing files for businesses and consumers with devices with bigger screens than 10.1-inch, such as iPad Pro) office suite by Microsoft for mobile devices.

Originally released as Pocket Office on Windows CE v1.0 Handheld PCs in 1996, the app in its present form is now available for tablet computers and smartphones running the Windows 10 Mobile, Windows Phone, Android, and iOS mobile operating systems. It was previously available for Windows Mobile and Symbian.
