A tree mounted tarp device couples a tarp to a tree under branches of the tree. The device includes a plurality of panels pivotally coupled together such that the panels are formable into a closed loop wrapping around a trunk of a tree. Each of a plurality of hooks is coupled to and extends from a top end of an associated one of the panels. Each of the hooks is directed towards a center of the closed loop for engaging the trunk of the tree facilitating suspension of the panels at a fixed height on the trunk of the tree. A tarp is coupled to the panels by a frame coupled to the panels. The frame supports the tarp in a deployed position wherein the tarp extends outwardly relative to the panels such that the tarp extends around the trunk of the tree under branches of the tree.
