Greece at the 1948 Winter Olympics

Greece competed at the 1948 Winter Olympics in St. Moritz, Switzerland, which were held from 30 January to 8 February 1948. The country's participation in St. Moritz marked its second appearance at the Winter Olympics since its debut in 1936. The athlete delegation of the country was composed of one competitor, alpine skier Fotis Mavriplis. He would be designated as the flag bearer for the nation during the opening ceremony.

Mavriplis would first compete in the men's downhill event against 118 athletes. There, he would place 101st. He was also entered in the men's combined event which requires both a downhill and slalom time. He would not compete in the slalom and therefore is unplaced in the rankings of the event.
