Sunshine Sketches of a Little Town is a sequence of stories by Stephen Leacock, first published in 1912. It is generally considered to be one of the most enduring classics of Canadian humorous literature. The fictional setting for these stories is Mariposa, a small town on the shore of Lake Wissanotti. Although drawn from his experiences in Orillia, Ontario, Leacock notes: "Mariposa is not a real town. On the contrary, it is about seventy or eighty of them. You may find them all the way from Lake Superior to the sea, with the same square streets and the same maple trees and the same churches and hotels."

Stephen P. H. Butler Leacock was a Canadian teacher, political scientist, writer, and humourist. Between the years 1915 and 1925, he was the best-known English-speaking humourist in the world. He is known for his light humour along with criticisms of people's follies.
