Christa Luding-Rothenburger (née Rothenburger, born 4 December 1959) is a former speed skater and track cyclist.

First she was told to stick to skating, but finally the president of the East German sports federation gave her permission to enter international cycling competitions.

This made her the second woman (after Sheila Young) to become world champion in both speed skating and cycling.

In October 1986, she was awarded a Star of People's Friendship in gold (second class) for her sporting success.

At the Winter Games in Calgary, Alberta, Canada, she won the gold medal in the 1000 m speed skating event and silver in the 500 m. Seven months later, she won the silver medal in the (1000 m) sprint in track cycling at the Summer Games in Seoul, South Korea.
