Walter Francis "Jack" Crangle (June 8, 1899 – August 31, 1944) was an American football fullback.

He was a member of Illinois' Big Ten Conference championship teams in 1919 and 1920.

[4] In his later years, he worked for the Aluminum Company of America and operated a filling station north of Columbia, Missouri.

[1][5] Following Crangle's death in 1944, Jack Ryan of the Chicago Daily News wrote that Crangle "rates high among the many good backs Bob Zuppke developed at the state university.

"[4] Howard Millard of the Decatur Review wrote: "It doesn't seem possible that Jack Crangle, the big, easy going, likeable fellow, probably the greatest fullback in all Illinois University history, is dead.
