Marianna "Muffy" Davis (born December 1, 1972) is an American politician, former Paralympic cyclist, and alpine skier who served as a member of the Idaho House of Representatives for the 26A district from 2018 to 2021.

She was a top ranking junior skier and was poised to be named to the US ski team when an accident at the age of 16 left her paralyzed from the chest down.

On June 1, 2002, she was in a team of four disabled climbers who reached the summit of the 14,179 feet (4,322 m) Mount Shasta in California.
