凯兰书卷（或译凯尔经，Book of Kells）（爱尔兰语：Leabhar Cheanannais）是一部泥金装饰手抄本，是早期平面设计的范例之一。凯兰书卷约在西元800年左右由苏格兰西部爱奥那岛上的僧侣凯尔特修士绘制。这部书由新约圣经四福音书组成，语言为拉丁语。这是一本有着华丽装饰文本的圣经福音手抄本，每篇短文的开头都有一幅插图，总共有两千幅。

虽然福音书的文本包括几个从圣经的更早的版本Vetus Latina的段落，但主要是根据武加大译本写成。它是西方书法的代表作，亦代表了海岛艺术绘画的高峰。它也被大众认为是爱尔兰最珍贵的国宝。

The Book of Kells (Irish:Leabhar Cheanannais; Dublin, Trinity College Library, MS A. I. [58], sometimes known as the Book of Columba) is an illuminated manuscript Gospel book in Latin, containing the four Gospels of the New Testament together with various prefatory texts and tables. It was created in a Columban monastery in Ireland or may have had contributions from various Columban institutions from both Britain and Ireland. It is believed to have been created c. 800. The text of the Gospels is largely drawn from the Vulgate, although it also includes several passages drawn from the earlier versions of the Bible known as the Vetus Latina. It is a masterwork of Western calligraphy and represents the pinnacle of Insular illumination. It is also widely regarded as Ireland's finest national treasure.
