Ben Jeby (born Benjamin Morris Jebaltowsky; December 27, 1909 – October 5, 1985), was an American world champion middleweight boxer from the Lower East Side of New York City.

[1][2][3][4][5][6][7] Jeby was born on December 27, 1909, near Clinton and Delancey Streets in New York's teaming Lower East side to Jewish parents.

[10][11][12][13] On March 20, 1931, weighing 157.5 pounds, he defeated Len Harvey on points over 12 rounds in a unanimous decision at Madison Square Garden in New York City.

Jeby fought a rushing, mauling, body punching battle, at close range, for which Harvey had no answer.

The knockout loss, which came 1:30 into the first round, discouraged Jeby, but ultimately did not affect his plans to pursue the World Middleweight title.

[5][4] Chick Devlin fell soundly to Jeby in a fifteen-round points decision at New York's St. Nicholas Arena on November 21, 1932.

[3][19][20] Jeby defeated Canadian Frankie Battaglia, viewed as one of the world's best middleweights, by TKO at Madison Square Garden in a title fight on January 13, 1933.

[24] Jeby fought Vince Dundee to a draw over 15 rounds, keeping his title, at Madison Square Garden on March 17, 1933.

[26] Young Terry fell to Jeby in an NYSAC Middleweight Title bout at Dreamland Park in New Jersey in a fifteen-round points decision on July 10, 1933.
