Laura Elizabeth Rachel Troubridge (1858 – 15 March 1929) was a British diarist, letter-writer, artist and illustrator. A professional artist from an aristocratic background, she was known for her portraits of Queen Victoria and her family, and paintings of children and fairy subjects, generally in watercolour and pastel. Her book illustrations were admired by Oscar Wilde and Charles Dodgson. In 1966, her journals, giving an insight into Victorian life; and in 2000 correspondence with her fiancé during the period of their engagement, were published.
