In mathematics and computer science, a random tree is a tree or arborescence that is formed by a stochastic process. Types of random trees include:

• Uniform spanning tree, a spanning tree of a given graph in which each different tree is equally likely to be selected

• Random minimal spanning tree, spanning trees of a graph formed by choosing random edge weights and using the minimum spanning tree for those weights

• Random binary tree, binary trees with various random distributions, including trees formed by random insertion orders, and trees that are uniformly distributed with a given number of nodes

• Random recursive tree, increasingly labelled trees, which can be generated using a simple stochastic growth rule.

• Treap or randomized binary search tree, a data structure that uses random choices to simulate a random binary tree for non-random update sequences

• Rapidly exploring random tree, a fractal space-filling pattern used as a data structure for searching high-dimensional spaces

• Brownian tree, a fractal tree structure created by diffusion-limited aggregation processes

• Random forest, a machine-learning classifier based on choosing random subsets of variables for each tree and using the most frequent tree output as the overall classification

• Branching process, a model of a population in which each individual has a random number of children
