有机团结（organic solidarity），或译为有机连带，是一个社会学术语，用于描述一种依靠相互依赖的集体意识，当社会有较复杂的劳动分工时，就会显现这一特性。它与机械团结相对。

有机团结着重描述社会分工给个体所创造的实际或潜在利益，来达到个体为整个群体奉献或贡献力量的一种作用。当社会变得愈来愈复杂，分工愈来愈细，一个人想要遗世独立就非常困难。互相依赖对团体的存续极为重要。根据涂尔干的《社会分工论》，在一个以发展的社会中，机械团结将会被有机团结代替，之所以用这样的一个词，是因为这样的社会运作起来，如同人体内各器官运作一样。

In sociology, "mechanical solidarity" and "organic solidarity" refer to the concepts of solidarity as developed by Émile Durkheim. They are used in the context of differentiating between mechanical and organic societies.

According to Durkheim, the types of social solidarity correlate with types of society. Durkheim introduced the terms "mechanical" and "organic solidarity" as part of his theory of the development of societies in The Division of Labour in Society (1893). In a society exhibiting mechanical solidarity, its cohesion and integration comes from the homogeneity of individuals—people feel connected through similar work, educational and religious training, and lifestyle. Mechanical solidarity normally operates in "traditional" and small scale societies. In simpler societies (e.g., tribal), solidarity is usually based on kinship ties of familial networks. Organic solidarity comes from the interdependence that arises from specialization of work and the complementarities between people—a development which occurs in "modern" and "industrial" societies. Definition: it is social cohesion based upon the dependence individuals have on each other in more advanced societies. Although individuals perform different tasks and often have different values and interests, the order and very solidarity of society depends on their reliance on each other to perform their specified tasks. Organic here is referring to the interdependence of the component parts. Thus, social solidarity is maintained in more complex societies through the interdependence of its component parts (e.g., farmers produce the food to feed the factory workers who produce the tractors that allow the farmer to produce the food).
