泰山封禪，源於古代帝王封禪祭祀。封禪是古已有之的禮儀。按照《史記·封禪書》張守節《正義》解釋：“ 此泰山上築土為壇以祭天，報天之功，故曰封。此泰山下小山上除地，報地之功，故曰禪”
元封元年（公元前110年）三月，漢武帝率羣臣東巡，至泰山，派人在岱頂立石。之後，東巡海上。四月，返至泰山，自定封禪禮儀：至梁父山禮祠“地主”神；其後舉行封祀禮，在山下東方建封壇，高九尺，其下埋藏玉牒書；行封祀禮之後，武帝獨與侍中奉車子侯登泰山，行登封禮；第二天自岱陰下，按祭后土的禮儀，禪泰山東北麓的肅然山。封禪結束後，漢武帝在明堂接受羣臣的朝賀，並改年號元鼎為元封，割泰山前嬴、博二縣奉祀泰山，名為奉高縣。此後，漢武帝又曾五次來泰山舉行封禪儀式。
