Catharine Parr Traill (born Strickland; 1802 - 1899) was an English-Canadian author and naturalist who wrote about life in Canada, particularly what is now Ontario (then the colony of Upper Canada). Traill began writing children's books in 1818 like Disobedience; or, Mind What Mama Says (1819). She described her new life in Canada in letters and journals, and collected these into The Backwoods of Canada (1836), which continues to be read as an important source of information about early Canada. Catharine spent her years in Belleville writing about the natural environment. She often sketched the plant life of Upper Canada, publishing Canadian Wild Flowers (1865) and Studies of Plant Life in Canada (1885). She died in Ontario in 1899.
