Roald Edgar Aas (25 March 1928 – 18 February 2012) was a speed skater and cyclist from Norway.

Aas was the number two speed skater in Norway through the entire 1950s—initially after Hjalmar Andersen, later after Knut Johannesen.

Aas participated in all international championships between 1951 and 1960, almost always finishing in the top ten.

At the Oslo Winter Olympics, he won bronze on the 1500 m, while at the Squaw Valley Winter Olympics in 1960, he finally won gold, shared with Yevgeny Grishin, also in 1500 m. Aas also was a successful cyclist, winning the 1956 Norwegian Championships in both road cycling and track cycling.

For his achievements as both a speed skater and a cyclist, Aas was awarded the prestigious Egebergs Ærespris in 1956.
