We introduce a method of characterization of non-Markovianity using coherenceof a system interacting with the environment. We show that under the allowedincoherent operations, monotonicity of a valid coherence measure is affecteddue to non-Markovian features of the system-environment evolution. We alsodefine a measure to quantify non-Markovianity of the underlying dynamics basedon the non-monotonic behavior of the coherence measure. We investigate ourproposed non-Markovianity marker in the behavior of dephasing and dissipativedynamics for one and two qubit cases. We also show that our proposed measurecaptures the back-flow of information from the environment to the system andcompatible with well known distinguishability criteria of non-Markovianity.
