'''Embedded C++'''是[[嵌入式系统]]上使用的一种[[C++]]方言，由日本[[CPU]]大廠[[NEC]]、[[日立製作所|日立]]、[[富士通]]、[[东芝]]于1996年提出，也可以缩写作'''EC++'''。提出这一方言的目的<ref>{{cite web|title=EC++ Rationale|url=http://www.caravan.net/ec2plus/rationale.html|accessdate=2019-03-11|archive-date=2018-11-01|archive-url=https://web.archive.org/web/20181101094801/http://www.caravan.net/ec2plus/rationale.html|dead-url=no}}</ref>是在保持C++语言[[面向对象]]特性的同时，尽可能减小代码、提升执行效率、简化[[编译器]]。<br />
<br />
Embedded C++ 是C++的子集合。有某些C++的特性被移除：<br />
* [[多重繼承]]<br />
* [[虚继承|虛擬基礎類別]]<br />
* [[執行期型態訊息]]（typeid）<br />
* 新式C++轉型（static_cast, dynamic_cast, reinterpret_cast 和 const_cast）<br />
* '''mutable''' 型別<br />
* [[命名空间]]<br />
* [[例外处理 (编程)|异常处理]]<br />
* [[模板 (C++)|模板]]<br />
<br />
有些编译器也允许在 Embedded C++ 中使用部分 ISO/ANSI C++ 的特性。<ref>{{cite web |title=Embedded and Extended Embedded C++ |url=http://www.testech-elect.com/iar/extended_embedded_c++.htm |accessdate=9 December 2012 |deadurl=yes |archiveurl=https://web.archive.org/web/20130521152331/http://www.testech-elect.com/iar/extended_embedded_c++.htm |archivedate=2013-05-21 |df= }}</ref><br />
<br />
這套語言並不被其他的 C++專家看好。特別是C++之父[[比雅尼·史特勞斯特魯普]] 稱，"To the best of my knowledge EC++ is dead (2004), and if it isn't it ought to be."<ref>{{cite web<br />
