Thomas Otho Travers (25 September 1785 – 9 July 1844) was a soldier, a friend of (and later aide-de-camp to) Stamford Raffles, and author of The Journal of Thomas Otho Travers 1813-1820, published more than a century after his death. Travers' diary is a notable work used for understanding Raffles and for understanding that period in East India Company history. No volume of his diary before 1813 survives, although excerpts from the earlier period survive in a memorandum prepared by Travers at the request of Raffles second wife.
