A Dictionary of the English Language, sometimes published as Johnson's Dictionary, was published on 15 April 1755 and written by Samuel Johnson. It is among the most influential dictionaries in the history of the English language.

Samuel Johnson, often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The Oxford Dictionary of National Biography calls him "arguably the most distinguished man of letters in English history".
