Prince Johan Friso, 43, a son of Queen Beatrix of the Netherlands, was skiing outside the bounds of the ski resort with friends at the resort of Lech am Arlberg when he was hit by an avalanche, a spokesman for the state of Vorarlberg said.
No one else in the group was affected, the spokesman said.
The prince was under the snow for a "short period of time," the spokesman said. He was wearing an electronic beacon that helped rescuers quickly find him, he said.
The prince was airlifted to a hospital in Innsbruck, where he is in intensive care, authorities said. Doctors described the prince as stable but not out of danger, according to a statement from the queen.
Lech am Arlberg is in Austria's Vorarlberg state, a popular skiing area in western Austria.
The region's avalanche agency reported there was a considerable to great chance of avalanches in Lech on Friday. It cited new snowfall on top of a packed layer of snow that could cause snow slabs to slide off.
The prince gave up his right to the throne when he married in 2004 without Parliament's permission. He and his wife live in London with their two daughters.
