The Lillooet Icecap, also called the Lillooet Icefield or the Lillooet Crown, is a large icefield in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is about northwest of the towns of Pemberton and Whistler, and about north of Vancouver, British Columbia. The Lillooet Icecap is one of the largest of several large icefields in the Pacific Ranges which are the largest temperate-latitude glacial fields in the world. At its maximum extent including its glacial tongues it measures east to west and north to south; its central icefield area is approximately in diameter.
