平城天皇，日本第51代天皇，桓武天皇第一皇子，母親是藤原良繼之女藤原乙牟漏。諱小殿，783年改名安殿，又稱奈良帝。785年被立為太子，806年時因桓武天皇駕崩而繼位。在他任內廢除了冗官，改善行政與經濟問題，設置觀察使來監督地方官，使律令全面重建。但是在809年時，
平城天皇因為身體病弱，長期治療都無法改善，最後讓位於異母弟神野親王（嵯峨天皇），自己則隱居在平城京。
與藤原藥子
平城天皇為登基以前，納藤原繩主與藤原藥子所生之女為東宮妃，但是卻傳出皇太子與身為嶽母的藥子有曖昧的醜聞，憤怒的桓武天皇便將藥子趕出東宮。待
平城天皇一即位，又將藥子召回宮裏，並命藤原藥子出任尚侍一職。此時的藥子因有天皇做其後盾，讓其兄藤原仲成一起入宮幹預政事。之後
平城天皇因為病弱而讓位為太上天皇，藥子兄妹也隨之失勢。不料上皇的病竟在退位後好轉，由於他還年輕，仍然關心國政，於是就以上皇的地位發佈政令，使得嵯峨天皇與上皇分別成為兩個朝廷一般。起初嵯峨天皇對上皇與藥子等人有所忍讓，但到後來上皇卻催促希望朝廷遷都平城京，以便自己掌權。嵯峨天皇在忍無可忍的情況下，在810年九月十日剝奪藥子的官位，藥子與平城上皇隨即想逃往東國，卻受到坂上田村麻呂的軍隊阻擋，衹好失意的回到平城京。之後上皇剃發出傢，藥子服毒自殺，其兄藤原仲成也被殺，史稱“藥子之變”。
因為藥子之變的關係，原本被立為嵯峨天皇皇太子、即
平城天皇第三皇子高嶽親王被廢太子，改由桓武天皇第三皇子大伴皇子為太子。
平城天皇的兩位皇妃朝原內親王與大宅內親王，也在812年時辭去皇妃的位子。
平城天皇於824年過世，由於他住在平城京，故被稱為
平城天皇。他的日式謚號為“日本根子天推國高彥尊”，葬於楊梅陵。
