1980 Canadian Ladies Curling Association Championship

The 1980 Canadian Ladies Curling Association Championship, (nicknamed "The Lassie"), the Canadian women's curling championship, was held from February 23 to March 1, 1980 at Northlands Gardens in Edmonton, Alberta. Attendance for the event was just 4,538, with about 700 witnessing the final.

Team Saskatchewan, who was skipped by Marj Mitchell captured the championship by defeating Nova Scotia in the final 6–5. Saskatchewan had previously defeated British Columbia 7–4 in a tiebreaker and Ontario 7–5 in the semifinal. This was Saskatchewan's eighth title and first since and the only championship won by Mitchell. This was also Mitchell's last appearance in the national championship as she died from cancer in 1983.

Mitchell's rink would go onto represent Canada in the 1980 Royal Bank of Scotland World Women's Curling Championship, the women's world curling championship, which they also won.
