草原式住宅（Prairie Style）美国著名建筑师莱特（Frank Lloyd Wright ,1869~1959）于1900年前后设计的一系列住宅，这类住宅大多座落在郊外，用地宽阔，环境优美。建筑从实际生活需要出发，在布局、形体、以至取材上，特别注意同周围自然环境的配合，形成了一种具有浪漫主义闲情逸致及田园诗意般的典雅风格。草原式风格追求表里一致性，建筑外形尽量反映出内部空间关系，注意建筑自身比例与材料的运用，力图摆脱折衷主义的常套，造型效果犹如植物覆盖于地面一样。建筑往往利用垂直方向的烟囱将高高低低的水平墙垣、坡度平缓的屋面、层层叠叠的水平方向阳台与花台及舒展而又深深的挑檐统一起来。它既具有美国建筑的传统风格，又突破了传统建筑的封闭性，很适合于美国中西部草原地带的气候和地广人稀的特点。建筑以砖木结构为主，尽量表现材料的自然本色，重点装饰部分的花纹大多图案化的植物图形或由直线组成的几何图形。伊利诺州的威立茨住宅（Willitts House 1902）是草原式住宅的代表。
