Maria Morris Miller (1813–1875) was a Canadian artist from Halifax, Nova Scotia who is known for her botanical paintings and illustrations.

[4] Miller studied her craft in Halifax first at a school run by Eliza Thresher on Salter Street,[5] and later under the tutelage of a visiting British painter named L'Estrange.

[9] Soon after, Nova Scotia's Secretary of Agriculture and botanist, Titus Smith, asked Miller to paint a series of canvasses depicting local wildflowers.

[3] During the mid 1830s, aided by Smith's scientific input, Miller produced a large number of water colour drawings which later ended up in an important Halifax art exhibition in 1848.

[9] Smith provided botanical descriptions for Miller's first catalog of coloured lithographs entitled Wild Flowers of Nova Scotia.

[10][11][12] It was issued in 1840 by a London bookseller and local publisher, with the financial support of the province's lieutenant-governor Sir Colin Campbell.

The third catalog was entitled Wild Flowers of Nova Scotia and New Brunswick and was annotated by George Lawson, a botanist who founded the Botanical Society of Canada.
