Jimmy Walsh (July 18, 1883 – November 23, 1964) was an American boxer who claimed the World Bantamweight Championship on March 29, 1905, when he defeated Monte Attell, in a controversial six-round bout at the National Athletic Club in Philadelphia.

[2] His bout against Willie Shumaker on March 26, 1903 at the Essex Athletic Club in Boston was billed as the American 105 pound title and ended in a ten-round points decision in his favor, though he was down in the first round.

The draw ruling, in the opinion of the Boston Post, was a clear victory for Walsh as they wrote Desmond "nearly collapsed" by the final round.

The St. Louis Dispatch, noted that according to most spectators ringside, the "blow was a fair one", though it was a "terrific right hook", and did notable injury to Attell.

Controversy arose as to who won the bout as many observers considered the blow legal, and that "Walsh completely had Attell at his mercy throughout the entire contest.

[9] On January 29, 1909, Walsh met Jimmy Reagan at the Dreamland Rink in San Francisco for a twelve-round World Bantamweight Title match.

[13] He met Attell twice in non-title matches on April 3, 1913, in New York in a ten-round loss by decision and on October 24, 1912, in a twelve-round draw in Boston.

[17][2] On November 18, 1910, he defeated talented British boxer Sam Keller at New York's Fairmont Athletic club in a ten-round match.

[18] On November 23, 1910, he lost decisively to Monte Attell, who had recently held the bantamweight championship, in a ten-round match in San Francisco.

Attell evaded his opponent with clever footwork and rocked Walsh, in the brutal bout, with blows to the jaw, mouth, and nose.

[19] He fought Johnny Kilbane in a World Featherweight Title match on May 21, 1912, at the Pilgrim Athletic Club in Boston, Massachusetts, to a twelve-round draw decision.

[2] They had previously fought in a non-title match on May 30, 1911, in a twelve-round draw bout in Canton, Ohio, that was characterized as "full of clinches", with neither man "doing much hard work.

Wallace was a skilled featherweight who would later meet the great Benny Leonard, Lew Tendler, Freddie Welsh and Johnny Dundee in his career, though without achieving an impressive win loss record.

Despite never referring a world championship fight, he did referee bouts for world champions such as Battling Battalino, Benny Bass, Sammy Fuller, Charles 'Bud' Taylor, Kid Chocolate, Johnny Jadick, Isadore Schwartz, Fidel LaBarba, Frankie Genaro, Pancho Villa, Mike Ballerino, Johnny Dundee, Pete Latzo, and Kid Williams.
