Hilda Gwendolyn Strike (later Sisson, September 1, 1910 – March 9, 1989) was a Canadian track athlete and Olympic medalist. She was born in Montreal and died in Ottawa. Competing in the 1932 Summer Olympics, she won a silver medal in the 4×100 metre relay and a silver medal in the 100 metre losing to Stanisława Walasiewicz. At the end of the year, she was named Canada's outstanding female athlete of the year by The Canadian Press. In 1972, she was inducted into Canada's Sports Hall of Fame. When Walasiewicz was shot to death in 1980 during a store robbery, it was discovered that Walasiewicz had an intersex condition. Many subsequently argued that the gold medal should be given to Strike. At the 1934 Empire Games she won the silver medal in the 100 yards event. She also was a member of the Canadian relay team which won the silver medal in the 110-220-110 yards relay competition.
