Mary Letitia Martin (1815–1850) was an Irish writer who was known as the "Princess of Connemara". Educated at home in the upper-class style, she was fluent in numerous languages. She published two books in her lifetime, and a third was published posthumously.
After losing her fortune during the Great Famine, Martin and her husband went to Belgium for a time, where she contributed to periodicals. They sailed to America in 1850, but Martin died 10 days after arrival due to complications of premature childbirth.
