1973 Macdonald Lassies Championship

The 1973 Macdonald Lassies Championship, the Canadian women's curling championship was held February 26 to March 2 at the Charlottetown Curling Club in Charlottetown, Prince Edward Island.

Manitoba and Saskatchewan both finished round robin play tied for first with 8–1 records, necessitating a tiebreaker playoff between the two teams. Team Saskatchewan, who was skipped by Vera Pezer defeated Manitoba in the tiebreaker 6–4 to capture the championship. Saskatchewan defeated Manitoba in the final draw 7–5 in an extra end to force the tiebreaker.

It was the sixth overall title for Saskatchewan and their fifth in a row. This was also the third straight title for the Pezer rink, becoming the first rink to win three straight championships. After the win, the team decided to retire from competitive curling.

The Nova Scotia rink finished winless for the second time in three years and became the fourth rink to accomplish the dubious feat. Nova Scotia only scored 37 points, setting a then-record for fewest points scored in a single tournament. This broke the previous mark of 43 also set by Nova Scotia in.
