A liquid cartridge for supplying liquid to a liquid ejecting apparatus, includes: a liquid accommodating part for holding the liquid; a channel for allowing the liquid in the liquid accommodating part to flow to the outside of the liquid accommodating part; and a check valve for preventing air from getting into the liquid accommodating part via the channel in a case where the channel is opened to the atmosphere with the channel faced upward and allowing backward flow of liquid from the liquid ejecting apparatus to the liquid accommodating part while the channel is connected to the liquid ejecting apparatus.
