Ryūichi Inamura (稲村 隆一, Inamura Ryūichi, 7 March 1898 – 20 November 1990) was a Japanese peasant movement activist and politician who served four terms in the House of Representatives. Active in the prewar agrarian and leftist movements, he belonged successively to the Japanese Communist Party, the Labour-Farmer Party, the Social Masses Party, and the Tōhōkai, before joining the Japan Socialist Party after the war. He was purged from public office during the Allied occupation and later returned the Order of the Sacred Treasure in protest against its award to Ryōichi Sasakawa. His younger brother was politician Junzō Inamura and his nephew was Toshio Inamura.
