Turkey sent a delegation to compete at the 1998 Winter Olympics in Nagano, Japan from 7–22 February 1998. This was Turkey's 12th time appearing at a Winter Olympic Games. The Turkish delegation to Nagano consisted of a single alpine skier, Arif Alaftargil. In the men's slalom, he finished in 29th place.

The Turkish Olympic Committee was recognized by the International Olympic Committee on 1 January 1911. They have participated in almost every Summer Olympic Games since, except for 1920, 1932, and the boycotted 1980 Summer Olympics. Since their first Winter Olympics participation at the 1936 Winter Olympics, Turkey has only missed three editions of the Winter Games, the 1952, 1972, and the 1980 Winter Olympics. Nagano was Turkey's 12th appearance at a Winter Olympics. The 1998 Winter Olympics were held from 7–22 February 1998; a total of 2,176 athletes took part, representing 72 National Olympic Committees. The Turkish delegation to Nagano consisted of a single alpine skier, Arif Alaftargil. He was chosen as the flag bearer for the opening ceremony.
