Rutgerus (Rudie) Liebrechts (born 6 September 1941) is a former Dutch speed skater and racing cyclist.

He had his biggest international successes at the World Allround Speed Skating Championships, where he twice won a bronze medal overall.

In 1961 in Gothenburg he finished behind his compatriot Henk van der Grift and the Russian Viktor Kosichkin, while in 1964 in Helsinki he followed the Norwegian Knut Johannesen and Viktor Kosichkin, again.

At the 1964 Winter Olympics in Innsbruck he missed out on medals, finishing 10th in the 1500m, 8th in the 5000m, and a close 4th on the 10,000m.

Rudie Liebrechts also was a reasonably successful cyclist at the national level; in 1965 he won the tour of Gouda.
