Summary: In the present paper we construct quantum Markov chains associated with open quantum random walks in the sense that the transition operator of a chain is determined by an open quantum random walk and the restriction of the chain to the commutative subalgebra coincides with the distribution \(\mathbb{P} _ \rho\) of the walk. This sheds new light on some properties of the measure \(\mathbb{P} _ \rho \). For example, this measure can be considered as the distribution of some functions of a certain Markov process.
