An apparatus for supplying a coating solution, and a system for supplying a coating solution are provided to remove the bubble and impurities of a coating solution without using a filter tank. An apparatus for supplying a coating solution comprises a canister(106) where a coating solution storage container(104) is mounted and which is provided with a first pressurization pipe(108) where an inert gas such as N2 is injected; a buffer tank(122) which is connected with the canister by a first supply pipe(112) and is provided with a second pressurization pipe(124) where an inert gas such as N2 is injected and a vacuum vent(126) for venting the internal air; a pump(140) which is connected with the buffer tank by a second supply pipe(128) and pumps a coating solution(102); and a dispense nozzle(136) which is connected with the pump by a third supply pipe and dispenses the coating solution.
