Dorita Fairlie Bruce (1885–1970) was a British children's author who wrote the popular Dimsie series of books published between 1921 and 1941. Her books were second in popularity only to Angela Brazil's during the 1920s and '30s.
She was a pioneer in creating series of books which followed a group of girls throughout their schooldays and even beyond. Her Dimsie, Nancy and Springdale series all follow this pattern, which was widely imitated.
The Colmskirk sequence, a set of nine novels for young adults, widened her scope, dealing with a group of families in the Scottish countryside around Largs from the seventeenth century to the twentieth. 
Bruce was involved with the Girls' Guildry for over thirty years. She contributed factual articles to the Lamp of the Girls' Guildry magazine and Girls' Guildry plays a role in her Nancy series and gets a mention in her Dimsie series. The Girls' Guildry later merged with similar organisations to become the Girls' Brigade.
