Google云端推送（英语：Google Cloud Messaging，简称GCM）是一项免费服务，帮助开发者从服务器发送数据到安装了他们的应用进程的Android设备上，或从服务器到其Chrome浏览器应用进程或扩展。Android云端推送服务第一次亮相是在2012年6月27日在旧金山Moscone中心举行的Google I/O 2012。Chrome上的推送服务在Google I/O 2013之前发布，官方博客文章题为“用推送消息构建高效的应用进程和扩展”。

Google云端推送（GCM）取代了beta版本的Android云端至设备推送（英语：Android Cloud to Device Messaging，简称C2DM）。免费服务可以发送一个轻量级的从服务器获取的新消息通知到Android应用进程。较大的消息可以发送有效载荷的数据为4 KB。

Google Cloud Messaging (commonly referred to as GCM) is a mobile service developed by Google that enables third-party application developers to send notification data or information from developer-run servers to applications that target the Google Android Operating System, as well as applications or extensions developed for the Google Chrome internet browser. It is available to developers free of charge. The GCM Service was first announced in August 2013 as a successor to Google's now-defunct Android Cloud to Device Messaging (C2DM) service, citing improvements to authentication and delivery, new API endpoints and messaging parameters, and the removal of limitations on API send-rates and message sizes.
