The invention discloses an offshore wind power foundation scouring protection unit and protection system, and relates to the technical field of offshore wind power foundations. The offshore wind power foundation scouring protection unit comprises a bottom plate and a flow guide plate, the bottom plate is used for being laid on a seabed corresponding to an offshore wind power foundation, the flow guide plate is arranged on the bottom plate and extends in the first direction, and the flow guide plate is provided with an incident flow face and a back flow face in the second direction perpendicular to the first direction. The incident flow surface is an inclined cambered surface and is used for disturbing ocean current flowing to the offshore wind power foundation, the back flow surface is arranged on the side, away from the incident flow surface, of the guide plate, and at least part of the bottom plate is arranged on the side, away from the back flow surface, of the guide plate. The offshore wind power foundation scour protection unit can be suitable for the pile foundation and the jacket foundation at the same time, is convenient to install, can be laid before the pile foundation is installed, guarantees scour protection of the offshore wind power foundation, and is low in cost.
