Simula，一种编译式的编程语言，在1960年代在奥斯陆的挪威电子计算中心（Norwegian Computing Center）开始被发展出来，主要的设计者是奥利-约翰·达尔（Ole-Johan Dahl）与克利斯登·奈加特。被开发了Simula I与Simula 67两代。它承继了ALGOL 60的基础，被认为是第一个面向对象编程的编程语言。

Simula影响了Smalltalk以及接下来所有的面向对象编程编程语言，如比雅尼·斯特劳斯特鲁普在设计C++语言时，将许多Simula 67的特性引入C++之中。

Simula is the name of two simulation programming languages, Simula I and Simula 67, developed in the 1960s at the Norwegian Computing Center in Oslo, by Ole-Johan Dahl and Kristen Nygaard. Syntactically, it is a fairly faithful superset of ALGOL 60.

Simula 67 introduced objects, classes, inheritance and subclasses, virtual procedures, coroutines, and discrete event simulation, and features garbage collection. Also other forms of subtyping (besides inheriting subclasses) were introduced in Simula derivatives.
