Wynona Croft Mulcaster (April 10, 1915 – August 25, 2016) was a Canadian painter and teacher from Saskatchewan, best known for her prairie landscapes.

[1][3] Mulcaster participated in Emma Lake Artist's Workshops led by Joseph Plaskett, Will Barnet and Kenneth Noland.

[6] Otto Rogers (born 1935) attended Saskatoon Teacher's College in 1952-53, where Mulcaster introduced him to cubism, a style he was to adopt for himself.

Mulcaster said his paintings were marked by a personal realism, recording the people, landscape, and animals with restraint, freshness and honesty.

She helped to get a pavilion built for the club on the Exhibition grounds, and managed to obtain noted guest instructors for riding clinics.

[1] Richard Simmins, first director of the Norman Mackenzie Art Gallery in Regina when it opened in 1953, arranged an exhibition of Ten Artists of Saskatchewan 1955.

He featured young landscape artists such as Mulcaster, Reta Cowley and Dorothy Knowles and abstract painters such as Henry Bonli who later became well known.

[11] In March 1975 her work was included in an exhibition of Major Saskatchewan Artists at the Mendel Art Gallery in Saskatoon.
