Miroslav "Miro" Zajonc (or Zayonc; born 10 June 1960) is a Slovak-born luger who competed for Czechoslovakia, Canada, and the United States.

Competing for Canada, he won the gold medal in the men's singles event at the 1983 FIL World Luge Championships in Lake Placid, New York, in four record breaking runs.

His victory created problems for the Soviet coaching staff as he defeated Danilin on a Soviet-built sled purchased from them just months prior to the race.

Despite sliding his best at the time, Zajonc was unable to compete at the 1984 Winter Olympics in Sarajevo, due to not having US citizenship.

His injury prevented him from competing in singles and he would finish 11th in the men's doubles event for the US team,[6][7] sliding with a special cast on his right foot.

The East German team requested to inspect Zayonc's injury, thinking he might be faking it to gain a competitive advantage using the pointed cast.
