仪式化（Ritualization），为动物行为学名词，用于解释在沟通信号演化过程中，某些行为模式失去其弹性及原先功能，而演变成一个固定模式（以传达消息）之现象。

Ritualization is a behavior that occurs typically in a member of a given species in a highly stereotyped fashion and independent of any direct physiological significance.

Ritualization is also associated with the work of Catherine Bell. Bell, drawing on the Practice Theory of Pierre Bourdieu, has taken a less functional view of ritual with her elaboration of ritualization.
