Francis Johnson (c. 1795/96 – 29 January 1876) was a British linguist. He taught Sanskrit, Telugu and Bengali at the East India Company College between 1824 and 1855. He compiled a comprehensive Persian, Arabic, and English dictionary, which he published in 1852 and which is the main thing he is remembered for. In 1829, Johnson published an expanded edition of Richardson's Persian-Arabic-English dictionary, which was presented as the third edition of Richardson's dictionary (the second edition of Richardson's was in year 1810). The dictionary presented Persian and Arabic words and translated them to English. The 1852 edition was much more comprehensive than the 1829 edition.
