A liquid discharge apparatus includes a liquid discharge head to discharge liquid to a medium and a liquid storage container. The liquid storage container includes a reservoir portion, a liquid injection portion, a liquid holding unit, and a liquid guide portion. The reservoir portion reserves the liquid that is supplied to the liquid discharge head. The liquid injection portion allows a liquid injection container for injecting the liquid into the reservoir portion to be inserted in the liquid injection portion in a first direction. The liquid holding unit is provided at a position spaced apart from the liquid injection portion and is capable of holding the liquid. The liquid guide portion guides the liquid from the liquid injection portion to the liquid holding unit in a second direction intersecting with the first direction.
