Nobuhiko Higashikuni (東久邇 信彦, Higashikuni Nobuhiko; 10 March 1945 – 20 March 2019) was a Japanese aristocrat and former Imperial prince. The first grandchild of Emperor Hirohito, he was the eldest son of Shigeko, Princess Teru, the Emperor's eldest child. He was thus a maternal nephew of the Emperor Emeritus Akihito and cousin of Emperor Naruhito. His father was Morihiro Higashikuni, a grandson of Emperor Meiji.
