Taipei (also known as Taipei!) is a mahjong solitaire game developed and released by Dave Norris for Windows PCs in May 17, 1990 (with v3.1).

Originally developed as a side-project at Microsoft, Taipei is the earliest Windows adaptation of mahjong solitaire (with earlier internal versions supporting Windows 1.x and Windows 2.x, one of the few games to do so). The v3.1 version was released publically as donationware, featured only one layout (the traditional "Turtle"), and uses a randomized "seed" generator.

Along with some other internal games developed at Microsoft, an updated version of Taipei (v4.0) was included as part of the Microsoft Entertainment Pack for Windows compilation. This version replaces the single layout with seven new layouts (Standard, Bridge, Castle, Cube, Glyph, Pyramid, or Spiral) while removing some of its features (including the ability to resize the window). This version was later included in some OEM desktop computer configurations (along with other games from the Microsoft Entertainment Pack series) and was included in The Best of Microsoft Entertainment Pack. It is considered a predecessor to Microsoft's later mahjong solitaire games Mahjong Titans and Microsoft Mahjong.

The game later received an updated v5.0 nagware release on August 12, 1991, adding the ability to create new tile layouts. The classic "Turtle" layout was also brought back (under the name Dragon).
