D语言(Dlang)是由Digital Mars公司开发的编程语言，起因是为了改进C＋＋。它与C二进制兼容（不完全），可编译为本地码，有GC也可手动管理内存，语法上借鉴多种语言，模板则在C＋＋的基础上做了相当大的扩充。D 语言既有 C 语言的强大威力，又有 Python 和 Ruby 的开发效率。它是一种集垃圾回收、手工内存操作、契约式设计、高级模板技术、内嵌汇编、内置单元测试、Mixin 风格多继承、类 Java 包管理机制、内置同步机制、内建基本运行时信息的系统级编程语言。

D语言是一种通用的系统和应用编程语言。它是比 C++ 更高级的语言，同时还保持了生成高效代码以及直接访问操作系统API和硬件的能力。D 很适合于编写从中等规模到那些由团队合作完成、数百万行代码规模的各种程序。D 易于学习，为编程者提供了很多便利，并且适用各种野心勃勃的编译器优化技术。

D 不是脚本语言，也不是一种解释型语言。它不需要虚拟机、宗教、或者高于一切的哲学。它是给实际的编程者使用的实际的语言，它帮助编程者快速、可靠的完成易于维护、易于理解的代码。

D 是数十年来实现多种语言编译器的经验的积累，是用那些语言构造大型工程的尝试的积累。D 从那些语言（主要是 C++ ）那里获得了灵感，并使用经验和现实世界中的实用性来驯服它。
