Thymeleaf是个XML/XHTML/HTML5模板引擎，可以用于Web与非Web应用。
Thymeleaf的主要目标在于提供一种可被浏览器正确显示的、格式良好的模板创建方式，因此也可以用作静态建模。你可以使用它创建经过验证的XML与HTML模板。相对于编写逻辑或代码，开发者只需将标签属性添加到模板中即可。接下来，这些标签属性就会在DOM（文档对象模型）上执行预先制定好的逻辑。Thymeleaf的可扩展性也非常棒。你可以使用它定义自己的模板属性集合，这样就可以计算自定义表达式并使用自定义逻辑。这意味着Thymeleaf还可以作为模板引擎框架。
Thymeleaf的模板还可以用作工作原型，Thymeleaf会在运行期替换掉静态值。例如下面的html文件，当作为静态文件时，product name显示为Red Chair，当运行在容器中并提供product这个对象时，product name的值会自动替换为product.description对应的值。
