Hayato Ikeda (池田 勇人 Ikeda Hayato; December 3, 1899–August 13, 1965) born in Hiroshima Prefecture, was a Japanese politician and the 58th, 59th and 60th Prime Minister of Japan from July 19, 1960 to December 8, 1960, to December 9, 1963, and to November 9, 1964 respectively.

As Prime Minister, he advocated the "income-doubling plan" and "politics of patience and reconciliation," respectively emphasizing economic development of Japan while minimizing societal conflict. His was noted for resolution of several major labor disputes, including a long-running strike at Miike Mine of Mitsui Mining Company (the resolution of this strike was in fact the first act of the Ikeda cabinet.)

Takafusa Nakamura, a leading economic historian, described Ikeda as "the single most important figure in Japan's rapid growth. He should long be remembered as the man who pulled together a national consensus for economic growth." His plan predicted a 7.2 percent growth rate (thereby doubling GNP over ten years), but by the second half of the 1960s, average growth had climbed to an astounding 11.6 percent.

Ikeda was an understudy of Yoshida Shigeru earlier in life, and was called an "honor student" for his commitment to the ideas presented in the Yoshida Doctrine, although he was a strong personality himself. His 1952 resignation as Minister of International Trade and Industry was the result of a blunt remark in the Diet that "it makes no difference to me if five or ten small businessmen are forced to commit suicide," after Ikeda's policies favoring heavy industry were imposed.
