Moniek Kleinsman (born 3 November 1982) is a Dutch speed skater who was born in Bentelo, Overijssel, and currently resides in Wolvega. She competed at the 2006 Winter Olympics. Kleinsman got her first speed skating lessons at the age of four. A few years later, when she was getting more serious into the sport she was mainly focussing on short track speed skating, just like her brother. However, at the age of twelve she decided to concentrate on long track speed skating instead.
