Bartholomew Frederick Lloyd (fl c. 1841 - 1849) was a Scottish stationery and bookseller active in Edinburgh c. 1841 to c. 1849. Lloyd was part of the firm Caldwell, Lloyd, and Company with Thomas Pringle Caldwell as early as 1841. In 1844, Caldwell retired from the firm and Lloyd continued on as B.F. Lloyd and Company until at least 1849, when it appears the firm went bankrupt.
