The men's ski jumping at the 1928 Winter Olympics took place at the 70-meter (230 ft) Olympiaschanze in St. Moritz, Switzerland, on 18 February.

Thirty-eight competitors from thirteen nations competed, with the event being won by Norway's Alf Andersen ahead of countryman Sigmund Ruud and Czechoslovakia's Rudolf Burkert.

[1] Norway sent a strong contingent with four jumpers able to win the event, including reigning Olympic and world champion Jacob Tullin Thams.

World record holder Nels Nelsen from Canada was not permitted to participate due to financial problems.

This was complied with by the jury, resulting in falls by several favorites, including the most vocal speed increase proponents, Gérard Vuilleumier and Bruno Trojani.

The rest of the delegation consisted Alf Andersen, Sigmund Ruud—the oldest of the Ruud brothers—and Hans Kleppen.

[4] Other favorites were Rudolf Burkert,[3] who had won and the ski jumping part of the Nordic combined event,[5] and the host nation's Gérard Vuilleumier.

[3] Canada had originally planned to send two ski jumpers, Nels Nelsen and Melbourne McKenzie.

[7] In terms of points, the three Norwegians Andersen, Ruud and Thams were in the lead, ahead of Burket and Vuilleumier.

[3] In the break, a number of Central Europeans, including Vuilleumier and Bruno Trojani, asked for top speed.
