Microsoft Expression Web is a discontinued HTML editor and general web design software product by Microsoft. It was discontinued on December 20, 2012, and subsequently made available free of charge from Microsoft. It was a component of the also discontinued Expression Studio.

Expression Web can design and develop web pages using HTML5, CSS 3, ASP.NET, PHP, JavaScript, XML+XSLT and XHTML. Expression Web 4 requires .NET Framework 4.0 and Silverlight 4.0 to install and run. Expression Web uses its own standards-based rendering engine which is different from Internet Explorer's Trident engine.
