Microsoft Surface is a family of touchscreen-based personal computer, tablet, and interactive whiteboard hardware products designed and developed by Microsoft. The majority of them run the Windows operating system and use Intel processors.

The Surface line has served as Microsoft's umbrella brand for PCs since it was first introduced in 2012, marking the company's first entry in building its own branded computers. It has since expanded to comprise several generations of hybrid tablets, 2-in-1 detachable notebooks, a convertible desktop all-in-one, an interactive whiteboard, and various accessories, many with unique form factors. Microsoft is also consolidating all other Microsoft hardware products such as PC accessories under the Surface brand as of 2023.
