Arthur Wellesley Gray was a British Columbia cabinet minister and mayor. He is particularly noted for his work creating some of British Columbia's early provincial parks and Wells Gray Provincial Park is named for him. His colleagues usually called him by his nickname, "Wells".

Wells Gray Provincial Park is a large wilderness park located in east-central British Columbia, Canada. The park protects most of the southern, and highest, regions of the Cariboo Mountains and covers 5,415 square kilometres. It is British Columbia's fifth largest provincial park, after Tweedsmuir, Tatshenshini, Spatsizi and Northern Rocky Mountains.
