QWERTY是各国使用的、基于拉丁字母的标准打字机和计算机键盘布局。“QWERTY”是该键盘布局字母区第一行的前六个字母。键的安排顺序由克里斯多福·萧尔斯(Christopher Sholes)设计。

使用QWERTY排列的打字机在1874年投入批量生产。从此成为应用最广泛的人机接口,大部分的计算机都是使用QWERTY键盘。

QWERTY键盘安排次序的原则,是减少打字机在打字时连动杆之间的挤压及故障发生率的状况,因而要把常用字母隔开(不过像“E”“R”就在一起)。其他种类的键盘,如1932年奥古斯特·德沃夏克(August Dvorak)发明的德沃夏克键盘,为希望在已经不需要避免连动杆的挤压后,重新排列键位以提高打字速度,因此把元音及5个最常用的辅音安排在中间一行,以便交换左右手打字的频率,同时也有设计左手或右手为重的键位。但是因故无法量产,以至于德沃夏克键盘键盘的普及程度不如QWERTY键盘。

QWERTY is a keyboard layout for Latin script. The name comes from reading the first six keys appearing on the top left letter row of the keyboard (Q W E R T Y) from left to right. The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to Remington in 1873. It became popular with the success of the Remington No. 2 of 1878, and remains in use on electronic keyboards due to inertia, the difficulty of learning a layout that differs from the currently entrenched standard, the network effect of a standard layout, and the claim by some that alternatives fail to provide very significant advantages.
