A lightning protection system for a wind turbine with a tower, a nacelle, a blade hub and a blade attached to the blade hub is provided. The lightning protection system includes an inner conductor inside the blade, an outer conductor arranged outside the blade and in electrical communication with the inner conductor, a collecting conductor arranged at the front end of the nacelle and in electrical communication with the outer conductor and a down-conductor connected to ground and in electrical communication with the collecting conductor. The outer conductor and the collecting conductor have substantially a same distance to the rotational axis. Further, a wind turbine with such a lightning protection system is provided.
