A guild hosting or clan hosting service is a specialized type of web hosting service designed to support online gaming communities, generally referred to as guilds or clans. They vary from game server hosting in that the focus of such companies is to provide applications and communication tools outside of the gaming environments themselves.

Guild hosting services address a guild's basic need to have an online presence and allow guild members to communicate with each other outside of the game. While it is possible for any guild to do this on their own, setting up and maintaining a site requires constant maintenance, upgrades and integration of new software. One of the key reasons for the popularity of guild hosting services is their focus on relieving the guild from this overhead and freeing them up to spend more time playing the game.
