美國國家公園管理局
美國國家公園管理局（National Park Service）係美國內政部裡頭嗰一隻聯邦部門，佢係負責管理數量好多且整體雜亂嗰美國國家公園體系，含到了美國國家公園、國家紀念區、國家紀念地、國家歷史公園、國家歷史地點、國家軍史公園、國家戰地、國家休閒區、國家河川、國家海岸、國家湖岸、國家景觀散步小路、國家景觀河川等等。這隻部門係由美國國會在1916年8月25日通過哩一隻法令National Park Service Organic Act拕建起來嗰。國家公園管理局嗰局長係由內政部長認定嗰，但係人選還係要參議院同意才可以。箇下，美國國家公園管理局有21989隻員工，分別係去管理397隻地點(這裡頭嗰58隻係國家公園)。但係涉及到政治敏感嗰內容，故係佢隻網站在中國內地係上不去嗰。
