Microsoft Edge Legacy (often shortened to Edge Legacy), originally released as simply Microsoft Edge or Edge is a discontinued proprietary cross-platform web browser created by Microsoft. Released in 2015 along with both Windows 10 and Windows 10 Mobile, it was built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. It was not released for Windows 8.1 (includes desktop, RT, and phone), Windows Server 2012 R2, and versions released before them.

Microsoft Edge Legacy on desktop was superseded by "The New Microsoft Edge", also known as simply "New Edge" (based on the Chromium open-source project), on January 15, 2020. On Xbox consoles, it was superseded in September 23, 2021.

The end of Edge Legacy support on Windows 10 Mobile coincided with the end of support for that platform, on January 14, 2020, while support on desktop ended on March 9, 2021, ending a 14 month support transition grace period. Xbox System Software support ended on September 23, 2021, when it was replaced by New Edge.
