Dave Irwin (born July 12, 1954)[1] is a former alpine ski racer who represented Canada at two Winter Olympic Games and won a World Cup downhill.

He was one of the "Crazy Canucks", a group of Canadian downhill racers who rose to prominence on the World Cup circuit in the late 1970s.

[9] The first concussion was sustained on January 10, 1976 at the downhill race in Wengen, Switzerland — two weeks after his sole World Cup win at Schladming[3] — and resulted in five days in hospital.

The heavily twisting curve at the left-hand transition to the Alpweg is named after the Crazy Canucks, Ken Read and Dave Irwin who both fell there in 1976.

Irwin suffered a traumatic brain injury on a training run for an Export A Skier-Cross event on March 23, 2001 which put him in a coma for three days.
