John James "Joe" Greene PC QC DFC (24 June 1920 – 23 October 1978) was a Canadian politician.

[3] [citation needed] After graduating from the University of Toronto Schools, he served in the Royal Canadian Air Force during World War II and earned the Distinguished Flying Cross.

[1][4] Following the war, he earned a Bachelor of Arts from the University of Toronto and a law degree from Osgoode Hall.

In 1965, he became Minister of Agriculture in the cabinet of Lester Pearson,[1] one of the few non-farmers to hold the position and the first easterner in 54 years.

In 1968, he ran to succeed Pearson in that year's federal Liberal leadership convention, but despite giving what many say was the best speech, he came in fifth place.
