ClipBook Viewer is a discontinued utility included in the Windows NT family of operating system that allows users to view the contents of the local clipboard, clear the clipboard or save copied and cut items. A feature restricted version, called Clipboard Viewer, is available in Windows 9x and earlier.

ClipBook Viewer was first introduced in Windows for Workgroups 3.1.{{cite web|url = http://support.microsoft.com/kb/126746|title = Windows for Workgroups Version History|date = 1 October 1992|website = Support|publisher = Microsoft|last = |first = |accessdate = 2016-01-26}} It allows users to store clipboard contents in ClipBook pages, share the contents of the clipboard with other users{{cite web|url = http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/share_how_cb.mspx?mfr=true|title = To share a local ClipBook page|date = 2002|accessdate = 2016-01-26 |website = Windows XP Professional Product Documentation|publisher = Microsoft|last = |first = }} or save the clipboard contents to a file (with .clp extension) to reuse them later.{{cite web|url = http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/whatis_intro_cb.mspx?mfr=true|title = ClipBook Viewer overview|date = 2002|website = Windows XP Professional Product Documentation|publisher = Microsoft|last = |first = |accessdate = 2016-01-26}} (Clipboard files cannot be shared.) The View menu allows viewing clipboard contents in various formats such as plain text, Unicode, HTML, RTF and OLE private data. In Windows XP, it is not listed in the Start menu and can only be accessed through its executable file, ClipBrd.exe.{{cite web|url = http://windows.microsoft.com/en-us/windows-xp/help/setup/open-clipbook-viewer|archiveurl = https://web.archive.org/web/20150708001020/http://windows.microsoft.com/en-us/windows-xp/help/setup/open-clipbook-viewer|archivedate = 2015-07-08|title = How to quickly open the ClipBook Viewer|date = |accessdate = 2016-01-26|website = Windows XP Help|publisher = Microsoft|last = |first = }}

Windows NT relies on NetDDE and a Windows service called "Clipbook" (with small "b") to share ClipBook pages.{{cite web|url = https://technet.microsoft.com/en-us/library/cc784866%28v=WS.10%29.aspx|title = Clipbook (System Services for the Windows Server 2003 Family and Windows XP Operating Systems)|date = 2005|website = TechNet|publisher = Microsoft|last = |first = |accessdate = 2016-01-26}} Each shared page support an access control list that defines whether they can be seen, linked to, or modified.{{cite web|url = http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/clipbook_pagepermissions.mspx?mfr=true|title = Securing ClipBook pages|date = 2002|website = Windows XP Professional Product Documentation|publisher = Microsoft|last = |first = |accessdate = 2016-01-26}}

ClipBook Viewer has been removed from Windows Vista and later, although the ability to view clipboard contents has been implemented into the Clipboard History feature, which was introduced in Windows 10 and later.{{cite web|url=https://www.microsoft.com/en-us/windows/tips/clipboard-history|title=Clipboard History|publisher=Microsoft|accessdate=2025-01-03}}
