A liquid cartridge includes a cartridge main body comprising a liquid chamber and an end surface. The liquid cartridge also includes a communicating portion protruding from the end surface of the cartridge main body in a protruding direction which is perpendicular to a width direction. The liquid chamber includes a wide portion and a narrow portion which is narrower than the wide portion in the width direction, and the narrow portion is offset toward a first side of the cartridge main body in the width direction. When the liquid cartridge is oriented such that the communicating portion faces downward and liquid is stored in the narrow portion, a position of center of gravity of the liquid cartridge is offset toward the first side of the cartridge main body from an area occupied by the communicating portion when the liquid cartridge is viewed in a vertical direction.
