Euphemia "Betty" McNaught (October 8, 1901 – May 24, 2002) was a Canadian impressionist painter who focused primarily on landscapes and pioneer lifestyles in Alberta.

In 1942, McNaught was commissioned by Canadian Prime Minister William Lyon Mackenzie King to document the construction of the Alaska Highway.

Afterwards, she enrolled in the Ontario College of Art and Design, and studied under Group of Seven members Arthur Lismer and James Edward MacDonald.

After a brief absence due to her father's death and her job painting the Alaska Highway, she began teaching at the University of Alberta Department of Extension in Grand Prairie in 1955.
