{{Short description|Type of proprietary network protocol}}
'''Remote Desktop Protocol''' ('''RDP''') is a [[proprietary protocol]] developed by [[Microsoft Corporation]] which provides a user with a [[Graphical user interface|graphical interface]] to connect to another computer over a network connection.<ref name=":0">{{Cite web|last=Deland-Han|title=Understanding Remote Desktop Protocol (RDP) – Windows Server|url=https://docs.microsoft.com/en-us/troubleshoot/windows-server/remote/understanding-remote-desktop-protocol|access-date=2020-10-12|website=docs.microsoft.com|language=en-us|archive-date=October 17, 2020|archive-url=https://web.archive.org/web/20201017001806/https://docs.microsoft.com/en-us/troubleshoot/windows-server/remote/understanding-remote-desktop-protocol|url-status=live}}</ref> The user employs RDP client software for this purpose, while the other computer must run RDP server software.

[[List of Remote Desktop Protocol clients|Several clients]] exist for most versions of [[Microsoft Windows]] (including [[Windows Mobile]] but the support has ended), [[Linux]] (for example [[Remmina]]), [[Unix]], [[macOS]], [[iOS]], [[Android (operating system)|Android]], and other [[operating system]]s. RDP servers are built into the server and professional editions of Windows operating systems but not home editions; an RDP server for Unix and OS X also exists (for example [[xrdp]]). By default, the server listens on [[Transmission Control Protocol|TCP]] [[Computer port (software)|port]] 3389<ref name=MSKBDefaultPort>{{cite web |url=http://support.microsoft.com/kb/306759 |title=How to change the listening port for Remote Desktop |publisher=Microsoft |date=January 31, 2007 |access-date=November 2, 2007 |archive-date=November 4, 2007 |archive-url=https://web.archive.org/web/20071104083358/http://support.microsoft.com/kb/306759 |url-status=live }} Microsoft KB article 306759, revision 2.2.</ref> and [[User Datagram Protocol|UDP]] port 3389.<ref>{{cite web |url=https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?&page=64 |title=Service Name and Transport Protocol Port Number Registry |publisher=Internet Assigned Numbers Authority |date=January 9, 2015 |access-date=January 13, 2015 }}</ref>

Microsoft currently refers to their official RDP client software as [[Remote Desktop Connection]], formerly "Terminal Services Client".

The protocol is an extension of the [[ITU Telecommunication Standardization Sector|ITU-T]] [[T.120|T.128]] application sharing protocol. Microsoft makes some specifications public on their website.<ref name=rdesktop>{{cite web|url=http://www.rdesktop.org/#docs|title=rdesktop: A Remote Desktop Protocol Client|website=www.rdesktop.org|access-date=November 29, 2008|archive-date=December 1, 2008|archive-url=https://web.archive.org/web/20081201091916/http://www.rdesktop.org/#docs|url-status=live}}</ref>
