Martin Joseph Walsh (October 16, 1884 – March 27, 1915) was a Canadian amateur, later professional, ice hockey player.

When Walsh re-signed with Ottawa, players Fred Lake and Albert Kerr decided to turn down their Renfrew offers.

In 1911, Walsh scored ten goals in a Stanley Cup challenge match against Port Arthur, second only to Frank McGee's 14 in one game.

Like many other centre forwards during the earlier years of professional hockey, Marty Walsh had his strongest suit in close proximity to the opponent net, where he would often park himself for redirections or deflections.

The Ottawa Citizen, in its January 26, 1911 issue, described a goal against the Montreal Canadiens on January 21 during the 1910–11 NHA season, where Walsh had positioned himself right in front of Georges Vézina for the game-winning goal in overtime, and the puck had caromed off of Walsh and into the net after first having left teammate Jack Darragh's stick.

[11] The Ottawa Citizen from January 26, 1911, also pointed out that while Walsh couldn't skate like Cyclone Taylor, wasn't blessed with the beautiful foot work of Albert Kerr, and didn't show as spectacular as Bruce Ridpath, his absence was still dearly felt for the Ottawas when he was off the ice, and exemplified the claim with a 5-minute slashing penalty on Walsh during the January 21 game against the Montreal Canadiens, by which "the Ottawa defence was demoralized, their attack seemed to melt to pieces, and before the Kingstonian's penalty had expired Canadiens had tied the score.

"[11] Walsh's hovering around the opponent net earned him the nickname "Stick-around" Walsh from famous Montreal Victorias player Russell Bowie, but the January 26, 1911 issue of the Ottawa Citizen also claimed that "Marty's checking back has re[s]cued the Ottawa defence from many a perilous position this winter.

[12] Their plans changed when Kerr was lured out of retirement to play in the new Pacific Coast Hockey Association (PCHA).

In February 1915, Walsh entered the Gravenhurst Sanitorium for treatment, but when admitted, the doctors estimated he had only a short time left to live.
