John McMorran (19 June 1889 – 24 February 2003) was a verified American supercentenarian. He was, at the time of his death, the oldest living man in the United States and 2nd oldest living man in the world behind Yukichi Chuganji and the longest-lived man ever who never held the title of the oldest living man in the world.
He was born in Goodland Township, Michigan, the oldest child of George McMorran and Lydia Ingram. McMorran was the cousin of Representative Henry Gordon McMorran (1844–1929). His sister, Lillia Elizabeth Webb lived to the age of 103. In his youth, a fortune teller predicted that he would live to age 111, but this seemingly outlandish forecast proved conservative, as barely one in six people who reach 111 live as long as McMorran finally did. At the time of his death, he was a great-great grandfather to then 5-year-old Logan Saxton. He also smoked, drank, and ate greasy food.
