Jan Jelte Ykema (born 18 April 1963) is a former ice speed skater from the Netherlands, who represented his native country at two consecutive Winter Olympics, starting in 1984 in Sarajevo, Yugoslavia. In 1988 (Calgary) he won the silver medal in the men's 500 metres. The same year he won all of his three World Cup races. A year later Ykema retired from international competition to work in real estate business. During his career he won three national sprint titles (1982, 1987 and 1988) and three distance titles.

After retiring from skating, Ykema became addicted to cocaine, and this addiction lasted for about 15 years.

After he recovered he started giving lessons at secondary schools about his addiction.
