网状网络（英文：Mesh Network）是一种在网络节点间透过动态路由的方式来进行数据与控制指令的发送。这种网络可以保持每个节点间的连接完整，当网络拓蹼中有某节点失效或无法服务时，这种架构允许使用「跳跃」的方式形成新的路由后将消息送达传输目的地。

在网状网络中，所有节点都可与拓扑中所有节点进行连接而形成一个「局域网路」。网状网络与一般网络架构的差异处在于，所有节点可以透过多次跳跃进行数据通信，但它们通常不是移动式设备。网状网络可以视为是一种点对点的架构。移动式点对点网络与网状网络在架构上是非常相似的，只是移动式点对点网络还必须随时更新组态以因应各节点移动的情形。

A mesh network is a network topology in which each node relays data for the network. All mesh nodes cooperate in the distribution of data in the network.

Mesh networks can relay messages using either a flooding technique or a routing technique. With routing, the message is propagated along a path by hopping from node to node until it reaches its destination. To ensure all its paths' availability, the network must allow for continuous connections and must reconfigure itself around broken paths, using self-healing algorithms such as Shortest Path Bridging. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable. As a result, the network is typically quite reliable, as there is often more than one path between a source and a destination in the network. Although mostly used in wireless situations, this concept can also apply to wired networks and to software interaction.
