Mary Ann Hayward (nee Lapointe; born March 10, 1960) is a Canadian amateur golfer.

At the international level, Hayward won the United States Mid-Amateur Championship, becoming the only Canadian with this title.

[1] She started playing golf at age 10 but it was only in 1979, when she placed second at the Quebec amateur championship, that she chose to pursue the sport as a career.

[5] In September 1992, Hayward was selected to represent Canada at the world amateur golf championship.

However, the morning the event started, another golfer withdrew due to a severe migraine headache, and Hayward was announced as her replacement.

In 1997, Hayward recorded 3-under-par 69 at Sorel-Tracy for a 36-hole total of 142, to earn an exemption into the LPGA du Maurier Classic.
